In such systems, the cooling process involves a compressor, condenser, 10 In addition to essential components such as expansion elements and evaporators, there are also oil separators and dryers. through a complex mechanical structure supported by various control and safety equipment This is being implemented. This structure not only increases the initial investment cost of the system; also affects device weight, assembly difficulty, maintenance requirements and operating costs.

This brings with it, especially the increasing global demand for energy and climate change. Within the scope of this effort, the energy efficiency and environmental impact of cooling systems are becoming more critical. This has become a subject of evaluation. Accordingly, the refrigerants used are 20 Global warming potential (GWP) stands out as a decisive parameter in system design. It is emerging. R410A, R134a and similar refrigerants are commonly used in current applications, Although it offers acceptable performance values, due to its high GWP values It is at a disadvantage in terms of environmental regulations.

Thermosiphon-based systems, theoretically, have a capacity of 5 It offers significant advantages such as high heat transfer coefficients and low energy consumption. However, the practical application of thermosiphon and free cooling systems involved in known technology... There are various limitations in its applications. In particular, as capacity increases, the system volume... Growth, piping and placement challenges, loss of device compactness and production Problems such as increased costs arise. Also, there are 10 completely passively operating systems. The limited capacity control in thermosiphon systems makes them inefficient under variable load conditions. This makes the work more difficult. This situation arises because these systems are large-scale and... It is known as a significant factor that restricts its flexible use. In current technology, most systems are also based on the principle of free cooling. Active pressure and flow rate control over the circulation of the refrigerant within the circuit 15 This cannot be achieved; this means that system performance is highly dependent on environmental conditions. This leads to the use of a fluid with strong thermosiphon properties, such as R32, in such systems. Even if its usage is known, the fluid in question requires control such as a liquid pump and expansion valve. an effective and integrated approach to evaluating it within a hybrid structure, together with its elements The solutions are not adequately addressed in the known technology. 20 THE PURPOSE OF THE INVENTION The main objective of the invention is to thermoform the R32 refrigerant, which has a low global warming potential.

It is explained with the aim of being. 20 The invention described in detail below is R32, which has a low global warming potential. By utilizing the thermomechanical properties of the refrigerant, free cooling and A water cooling system that operates on the thermosiphon principle, is energy-efficient, and environmentally friendly. It is about developing the device. In the system as shown in Figure 1, the refrigerant circuit dissipates heat to the environment at a rate of 25. The main task is performed by the fan (1) and condenser (2). Fan (1), condenser (2) by creating a forced airflow over it, the refrigerant on the condenser surface This allows the condenser (2) to efficiently transfer its heat to the outside environment. Thanks to this air flow, the condenser The refrigerant circulating inside tends to condense, and heat transfer occurs. It accelerates. The condenser (2) is lighter and has a higher heat output compared to classic condensers. selected to have transfer efficiency, and the total weight and volume of the device It contributes to its reduction. 5 At the outlet of the condenser (2), the refrigerant transitions to a liquid phase predominantly state and at this point Liquid tank (5) comes into play. Liquid tank (5) is a refrigerant for the coolant circulating in the system. by creating a reserve volume, for periods of high thermal loading or sudden operation It ensures that the fluid volume is kept within safe limits during changes. Similarly When maintenance or service is required, the coolant is removed from the system in a controlled manner. It allows for temporary storage by taking it in this way. Also, instantaneous concentration. by ensuring the liquid line is kept completely filled with coolant in accordance with the requirements. It increases system stability. The expansion valve (8) is located on the refrigerant line from the liquid tank (5) outlet, a sudden pressure drop in a refrigerant that is in liquid state under high pressure 15 By creating this pressure drop, it increases the fluid's tendency to evaporate. The coolant reaches thermodynamic conditions suitable for heat extraction. Expansion valve (8), While supporting the system's free cooling behavior, it also works in conjunction with a liquid pump. It is positioned to have a positive impact on capacity and efficiency. The main component of the coolant circuit that extracts heat from the process water is the plate heat exchanger (3). 20 Plate heat exchanger (3) allows the coolant and process water to heat up without mixing, only between the plates. It enables heat transfer through the heat exchanger. Within this heat exchanger, the low level after expansion... Pressurized coolant tends to evaporate by absorbing heat from the process water; thus, the water The desired cooling is provided on the side. The heat exchanger (3) provides both free cooling and cooling of the system. It serves as the primary heat exchange point in hybrid operating modes. 25 The process water circuit consists of a stainless steel pressurized water tank, as shown in the hydraulic diagram in Figure 2. It starts with (6). The water tank (6) is for storing chilled water in a certain volume. By doing so, it helps the system to operate stably against sudden load changes. Made from stainless steel, it is resistant to corrosion and chemical effects. It is durable. The process water in the water tank (6) is circulated through the water pump (4) 30 Water pump (4) is used to continuously pump water between the plate heat exchanger (3) and the process line. 6 It ensures controlled circulation and maintains the continuity of heat transfer on the water side. is doing. Process water flows from the outlet of the water pump (4) through the piping line to the plate heat exchanger (3) It is directed. The water cooled in the heat exchanger (3) is returned to the heat exchanger outlet. It is sent to the tank (6) or directly to the process line. Thanks to this cycle, the water circuit is sent to the tank (6), 5 It forms a closed and controlled hydraulic loop in the form of a pump (4) and heat exchanger (3). Water The pipeline is constructed using PPRC piping during the manufacturing phase, ensuring leak-proofness and long service life. They are selected in line with their objectives. On the refrigerant circuit side, the thermosiphon property of R32 refrigerant is fundamental to the system. It constitutes one of the working principles. The phase change and density of the fluid 10 Thanks to the natural convection effect resulting from their differences, evaporation and condensation occur. Circulation between regions is achieved without the need for a mechanical compressor. This is natural. Circulation significantly reduces the system's energy consumption in free cooling mode. The liquid pump integrated into the system increases the pressure of the liquid coolant when needed. It supports circulation by increasing and improves system performance, especially under variable load conditions. It stabilizes. The system also includes a sight glass for monitoring fluid cleanliness and operational safety. Auxiliary elements such as driers are included, and the fluid status is monitored through the sight glass. It is observed that unwanted particles such as moisture and dirt are filtered out by the drier. All The components are mounted on a base and chassis structure, making the device compact, portable, and serviceable. It has been ensured that the device is presented as a usable whole. The legs allow the device to be lifted off the ground. by enabling the protection of the system, especially in rainy regions or in the event of potential flooding. a contribution is being made. Thanks to this integrated structure, the system preserves the energy advantages of the free cooling principle, A compact, 25-inch water heater that enhances capacity and efficiency control through integrated liquid pump and expansion valve. It operates as a low-maintenance and environmentally friendly chiller solution.
