Introduction. The development of renewable energy is a
key direction in achieving sustainable development goals,
including reducing the negative impact of the energy sector
on the environment and enhancing the energy efficiency of
production. Renewable energy sources have significant po-
tential due to their environmental friendliness and inex-
haustibility. However, their main drawback remains incon-
sistency, as energy production depends on natural
conditions that can change stochastically. This creates risks
for the stability of energy supply, especially in local energy
systems. Pharmaceutical production requires high preci-
sion in maintaining the climatic parameters of the prem-
ises, which is ensured by the simultaneous operation of
cooling and heating systems. The main source of cooling in
such enterprises is powerful refrigeration units. Rational
use of energy resources in this process is critically im-
portant. The FreeCooling technology allows significant re-
duction of cooling costs during the cold season by using ex-
ternal climatic conditions for cooling without involving
compressor units. At the same time, the heating of phar-
maceutical enterprises is traditionally based on the use of
thermal devices that operate on fossil fuels. A practical so-
lution for optimizing energy consumption is the implemen-
tation of heat pumps, which can use the cooling circuit as a
heat source. This allows efficient redistribution of energy
between systems and reduces fuel consumption in heating
installations, contributing to lower operating costs and en-
vironmental impact.
Scientific research and development work on improving the
efficiency of heat pumps have been conducted both in
Ukraine and worldwide for a long time. The prospects of
using heat pumps have been studied in works [1,2,3]. In
works [6,7,8], the efficiency of various types of heat pumps
has been evaluated. The authors [9, 10] have performed a
comparative energy analysis of heat pumps. Active re-
search is being conducted to create an effective control sys-
tem in the design of complex local energy supply systems
(clusters) using renewable energy sources [14,15,16].
The results of these studies confirm the prospects of in-
creasing energy efficiency through the use of low-potential
thermal energy systems of industrial enterprises for heat-
ing, air conditioning, hot water supply, and meeting the
technological needs of consumers.
Task Statement. Rational use of energy resources in the
pharmaceutical industry is critically important, as maintain-
ing stable climatic conditions in production facilities di-
rectly affects product quality. The implementation of en-
ergy-efficient technologies, such as heat pumps and
FreeCooling, not only reduces energy supply costs but also
enhances the environmental sustainability of the enter-
prise.
The aim of this work is to develop and implement an en-
ergy-efficient system that provides simultaneous heating
and cooling for a pharmaceutical enterprise with minimal
costs. The proposed solution is based on the use of a heat
pump with a heat source in the form of a refrigeration net-
work, which ensures continuous year-round operation of
the system according to production needs. The research
also aims to determine the optimal ratio between
FreeCooling and heat pump technologies to maximize cost
reduction, increase profitability, and automate processes
using a SCADA system.
Presentation of the Main Material
The heating system at pharmaceutical enterprises is of
great importance, as creating stable temperature and hu-
midity critically affects product quality, especially in the
production of medicines and storage of pharmaceutical
products. Typically, systems based on gas boilers, steam
boilers, or electric heaters are used. Their main disad-
vantages are carbon emissions into the atmosphere and
high fuel costs. Heat pumps are a more modern, efficient,
and environmentally friendly way of heating, which is be-
ginning to replace traditional systems. Their significant ad-
vantages are that they can provide efficiency up to 400%,
meaning for each unit of electrical energy, they can deliver
4 units of heat, they do not produce CO2 emissions and
help reduce the enterprise's environmental footprint, they
have significantly lower maintenance costs, and their use
requires less fuel expenditure compared to traditional
184

systems, modern heat pumps are capable of not only heat-
ing the premises but also cooling them in the summer,
which is important for maintaining a stable climate inside
the premises where pharmaceutical products are stored.
Also, heat pump systems can be integrated with other tech-
nologies for precise microclimate control, which is critical
for pharmaceutical enterprises.
The use of FreeCooling technology allows significant reduc-
tion in cooling production costs during the winter period.
The FreeCooling system uses external climatic conditions to
lower the temperature of the water circulating in the cool-
ing system without the need for compressor refrigeration
machines. This can significantly reduce electricity costs, es-
pecially in colder periods of the year when the outside tem-
perature is lower than the temperature that needs to be
maintained in the system.
Refrigeration machines TRANE consist of two TRANE refrig-
eration machines (launched in 2010) to maintain the cool-
ant at 6°C-12°C. The refrigeration machines XM№1, XM№2
each have 2 independent circuits in one refrigeration ma-
chine, which include two evaporators, two compressors,
two condensers, automation devices, and two remote con-
densers. XM№1 and XM№2 also have a FreeCooling sys-
tem with additional heat exchangers.
The refrigeration machines maintain the coolant tempera-
ture at 6°C-12°C. When the outside air temperature is
above 5°C, the refrigeration machines operate. Depending
on the load, the controller turns on one or both refrigera-
tion machines. When the outside air temperature is below
5°C, the refrigeration machines turn off. FreeCooling, in-
stalled on XM№1, is activated. When the water tempera-
ture in the cooling circuit exceeds 12°C, both refrigeration
machines are activated to reduce it.
An analysis of existing methodologies for building complex
systems was carried out. Based on the criteria of minimal
capital costs and maximum efficiency with minimal sea-
sonal impact, it was decided to install a water-to-water
heat pump. Using heat pumps in a configuration where the
cooling circuit serves as a heat source and heat is dissipated
in the heating circuit allows for the necessary heat ex-
change between continuously operating systems, resulting
in reduced fuel consumption for heating devices. In the ab-
sence of production and the need to maintain comfortable
conditions in the premises (e.g., on weekends), a low-ca-
pacity heat pump provided the necessary temperature in
the cooling network and prevented the operation of a more
powerful refrigeration machine.
To illustrate the operation of the heat pump system and the
FreeCooling system at a pharmaceutical enterprise, a math-
ematical model can be developed to describe the interac-
tion of the energy parameters of such systems and deter-
mine the efficiency of energy use.
The total energy consumption for heating or cooling prem-
ises at a pharmaceutical enterprise can be determined as:
(1)
where:
Etotal - total energy consumption for the operation of the
heat pump system.
This equation allows for the assessment of energy con-
sumption for heating or cooling depending on the COP
value, which can vary depending on temperature condi-
tions.
The FreeCooling system can use the outside temperature
to reduce cooling costs in the winter period. Mathemati-
cally, this can be expressed as:
, (2)
where:
Qcool - the amount of heat removed from the system
through FreeCooling;
Qext - the amount of energy transferred through FreeCool-
ing (this depends on the temperature difference between
the external environment and the internal premises);
Text - the temperature of the external environment;
Ttarget - the set temperature for starting FreeCooling, which
is optimal for cooling the premises.
An important part of this model is that FreeCooling actively
works when the outside temperature is low enough to pro-
vide cooling without the use of refrigeration machines. If
the outside temperature is higher than a certain threshold
Ttarget, the system switches to regular cooling using refriger-
ation machines.
Changes in energy tariffs can significantly affect the effi-
ciency of using heat pumps and FreeCooling systems. To
model this effect, the following model can be used, which
takes into account tariff changes throughout the day.
Let Pelec(t) - be the electricity tariff at time t, and Pgas(t) the
gas tariff at the same time. The energy cost model consid-
ering tariffs can be expressed as:
(3)
where:
Ecost(t) - energy costs for a specific time period t;
Qgas(t) - gas consumption for heating depending on time t.
Considering the variability of tariffs, the system can be con-
figured to use cheaper energy during periods when electric-
ity or gas tariffs are low.
For comprehensive management of the entire energy sys-
tem, a model can be created that combines all the afore-
mentioned components: heat pumps, FreeCooling, energy
tariffs. The total energy consumed and costs can be de-
scribed as follows:
(5)
where:
Eheat - energy spent on heating;
Ecool - energy spent on cooling (including FreeCooling);
This model allows for accurate calculation of energy re-
source costs depending on weather conditions, energy
185

tariffs, and the efficiency of using heat pumps and
FreeCooling.
For analysis, data obtained during the operation of the ex-
isting cooling system, which includes refrigeration ma-
chines with Free cooling function, a heat pump, and energy
consumption data during the cold season, were used. The
calculated economic efficiency results for the technologies
considered are shown in the Table.
For the pharmaceutical company "Darnitsa", a heat pump
of the Italian brand Aermec, model WRK0350HL was cho-
sen, designed for heat recovery from the refrigeration cir-
cuit (coolant temperature 6°C-12°C) to the heating system
(heat carrier temperature 45°C-65°C). This heat pump has
a thermal capacity of 103.8 kW and a cooling capacity of
81.9 kW, ensuring efficient operation in the heating and
cooling system. Additionally, it can be integrated with ex-
isting FreeCooling systems to optimize energy costs.

A result with + means that the use of the heat pump is economically feasible
A result with - means that the use of the heat pump is not economically feasible
One of the important features of the heat pump system is
the ability to automate its operation depending on changes
in electricity and natural gas tariffs. With modern control
systems such as SCADA, the heat pump's operating sched-
ule can be automatically adjusted, significantly reducing en-
ergy costs. SCADA software allows for monitoring and ana-
lysing energy consumption, as well as forecasting cooling
and heating needs for the next day
The software takes the following data from the database:
the cost of gas (updated once a month), the cost of electric-
ity (data updated hourly), the cost of electricity transmis-
sion and distribution (updated once a month). Based on the
received information, the actual cost indicator is calculated
and compared with the planned one. If the actual indicator
is below the threshold, the heat pump is allowed to turn on.
In the absence of emergencies and confirmation that all
other operating parameters are normal (heat carrier tem-
perature, coolant temperature, system pressure...), the
heat pump is turned on. If the actual indicator is above the
threshold, the controller prohibits the operation of the heat
pump until the actual indicator is below the threshold.
During commissioning, it was noted that by default, all heat
pumps are set to automatic control of the temperature of
the received heat carrier, assuming that the heat source is
conditionally infinite. This led to the fact that during daily
temperature fluctuations in the heat network and its
threshold values, the heat pump unloaded the compressors
(operated at 50% capacity) or stopped upon reaching the
set temperature. It was decided to "Reverse the control
scheme" to rebuild the automation scheme, moving the
control point from the heat consumer to the source. Thus,
the automation began to control the temperature of the
cold circuit, considering the heat consumer conditionally in-
finite. In the winter period, when the freon vapor temper-
ature is below the heat carrier temperature in the network,
to prevent emergency stops due to condensation tempera-
ture, the control of this parameter was transferred to an
external SCADA that allows or prohibits the operation of
the heat pump. Since the cooling system's cold consump-
tion is constantly higher than the heat pump's capacity, it
constantly operates at 100% load, transferring all the heat
to the heating system. This allowed eliminating partial load
mode and using the heat pump at maximum productivity.
One of the important features of heat pump systems is the
ability to automate their operation depending on changes
in electricity and natural gas tariffs. With the help of mod-
ern control systems such as SCADA, it is possible to auto-
matically adjust the heat pump's operating schedule, signif-
icantly reducing energy costs. SCADA software allows
monitoring and analysing energy consumption, as well as
forecasting cooling and heating costs for the next day. Real-
time dispatch control, data collection, processing, display,
and archiving, and SCADA control of the entire considered
cooling system is carried out using the software product
from Siemens – Desigo CC.
Desigo CC is an open integrated platform for building auto-
mation and dispatching. It simplifies operation, monitoring,
control, optimization, and management of facilities from a
single interface, enhancing comfort, efficiency, and safety.
Desigo CC provides the technological foundation for smart
buildings, offering an open and modular platform that
grows with management requirements.

The electricity tariff changes every hour and can be signifi-
cant for an industrial enterprise in Ukraine, depending on
many factors. The average price for a company, including
transmission and distribution, in February was 8.07
UAH/kWh excluding VAT. At the same time, the minimum
DAM price excluding transmission and distribution in Feb-
ruary was 0.5 UAH/kWh, and the maximum price was 10
UAH/kWh. The price differs more than 10 times. The price
difference is especially pronounced in the spring-autumn
period, which is due to solar generation.
The natural gas tariff is determined once a month on a con-
tractual basis. As of February 2025, the cost of 1m3 of gas is
UAH 16.97 excluding VAT.
The Desigo CC software, through an intermediate database,
allows automatic retrieval from the Market Operator's
website of the DAM tariff forecast and the natural gas cost
for the current period. The tariff data allows for the
calculation of ratio coefficients and the prediction of the
heat pump operation schedule for the current and next
day.
On the example of the SCADA video page from 20.02.2025
(Figure) it is seen that the time interval between 0:00 to
17:00 and from 22:00 to 24:00 has a positive ratio between
the natural gas tariff and electricity, so the system algo-
rithm allows the heat pump to operate, which is indicated
by a "green circle" next to the electricity tariff. In the period
from 17:00 to 22:00, when the ratio of the cost of natural
gas to electricity is unprofitable, the programmed algo-
rithm does not give a command for the heat pump to oper-
ate. On the video page, this period is marked with "gray cir-
cles". After the end of the day, the data is automatically
updated with the calculation of the heat pump operation
schedule depending on the DAM tariffs and the cost of nat-
ural gas.
Figure. SCADA page of Decigo CC with the structural diagram of the Aermec heat pump, Model WRK0350HL, and auto-
matic scheduling of the operation schedule depending on the tariffs
According to the calculation of daily electricity consump-
tion, cold and heat production, in the case of the heat pump
operating in constant mode, i.e., without considering tariff
variability, the savings from using the technology amount
to 881 UAH/day. In the case of the heat pump operating in
adaptive mode, considering the ratio of energy carrier
costs, the savings from using the technology amount to
1024 UAH/day. Thus (on the example of 20.02.2025), the
profitability of the heat pump operation increases by 16%
and amounted to an additional 143 UAH/day. On an annual
scale, the potential increase in profitability could amount
to an additional UAH 35 - 40 thousand.
Conclusion:
Modern heating and cooling technologies, such as heat
pumps and FreeCooling systems, are important tools for in-
creasing the energy efficiency of pharmaceutical enter-
prises. They not only reduce fuel and electricity costs but
also help to reduce the environmental impact of produc-
tion. Taking into account changes in energy tariffs and au-
tomating the operation of heat pumps can significantly in-
crease the economic efficiency of the enterprise, which is
an important factor in the current competitive market con-
ditions.

The article investigates the efficiency of using a heat pump to simultaneously generate heat and cold at a pharmaceutical enterprise in order to reduce energy costs. The proposed scheme, where the source of heat is a refrigeration network with constant parameters, ensures the stability of temperature conditions required for technological processes and product storage. The economic feasibility of using a heat pump in comparison with such a technology as freezing is analyzed at different periods of the day. Particular attention is paid to the automatic regulation of the system through the SCADA system, which minimizes the human factor and guarantees continuous maintenance of the required conditions. Taking into account the requirements of pharmaceutical production, including the need to comply with strict temperature parameters, a water-to-water heat pump was chosen. This scheme allows efficient use of energy between the cooling and heating systems, which ensures stable climate conditions in production and storage facilities. During periods of downtime, the heat pump maintains the required temperature in the refrigeration network, preventing the use of energy-intensive chillers. This solution increases energy efficiency, reduces operating costs, and meets the requirements of good manufacturing practice. Promising areas for further research include the development of algorithms for automatic control of heat pumps, as well as the integration of energy storage systems to improve efficiency under variable load conditions.  У статті досліджено ефективність використання теплового насоса для одночасного отримання теплоти та холоду на фармацевтичному підприємстві з метою зниження енергетичних витрат. Запропонована схема, де джерелом теплоти виступає холодильна мережа з постійними параметрами, забезпечує стабільність температурних режимів, необхідних для технологічних процесів та зберігання продукції. Аналізовано економічну доцільність використання теплового насоса в порівнянні з такою технологію як FreeCooling, у різні періоди доби. Особливу увагу приділено автоматичному регулюванню роботи системи через SCADA-систему, що мінімізує людський фактор і гарантує безперервне підтримання необхідних умов. З урахуванням вимог фармацевтичного виробництва, включаючи необхідність дотримання строгих температурних параметрів, вибрано тепловий насос «вода-вода». Така схема дозволяє ефективно використовувати енергію між системами холодо- та теплозабезпечення, що забезпечує стабільність кліматичних умов у виробничих та складських приміщеннях. У періоди простою тепловий насос підтримує необхідну температуру в холодильній мережі, запобігаючи використанню енергоємних холодильних машин. Це рішення підвищує енергоефективність, зменшує експлуатаційні витрати та відповідає вимогам належної виробничої практики. Перспективними напрямками подальших досліджень є розробка алгоритмів автоматичного керування тепловими насосами, а також інтеграція систем накопичення енергії для підвищення ефективності в умовах змінного навантаження.
