With an air-to-water heat pump system whose operating efficiency is improved in mode 5 It is related. Today, air-to-water heat pumps are used for heating and cooling residential buildings. The use of heat pump systems is becoming widespread. These systems convert air into water for heating. Pump systems meet the hot water and heating needs of a house, especially during the winter months. It is used to meet the needs of the water supply during the day, while in summer it is used to cool the environment and also to meet the need for hot water. It is used to meet. Air-to-water heat pump systems, refrigerant line in heating and cooling mode. It can be examined via two lines: the refrigerant line and the water line. The refrigerant line and this line 15 All the components on it are referred to as the system's external unit, and these are all... The residential building is located outside the building. The water line and all components on this line are hydroelectric. They are called lines or indoor units, and all of these are within the installation that connects to the residential indoor environment. They are positioned so that the coolant and water are placed together in heating and cooling mode. The critical component through which heat is transferred is the plate heat exchanger located in the outdoor unit. 20 Switching from heating mode to cooling mode in air-to-water heat pump systems. During this process, the flow on the refrigerant side of the plate heat exchanger is controlled using a four-way valve. The direction of flow reverses, while the flow direction on the water side remains constant. In heating mode, While cross-flow occurs in the plate heat exchanger, only 25 is available when switching to cooling mode. Due to the change in the direction of the refrigerant flow, the flow becomes parallel. This situation The logarithmic mean temperature directly affects the capacity obtained from the plate heat exchanger. plate heat exchangers cause a decrease in the log mean temperature difference. This causes a decrease in capacity. In this case, the system is in cooling mode. This leads to a decrease in productivity while working. 30 2 A European patent document, numbered EP3943822, which is included in the prior art, The document refers to heat pump systems and describes the heat pump systems mentioned.

It enables the creation of cross-flow. This allows the plate heat exchanger, especially in cooling, to be used effectively. In this mode, instead of operating under parallel flow as in the known state of the technique... By enabling it to operate under cross-flow, the capacity of the plate heat exchanger is increased, and this 5 This situation also applies to the operation of the air-to-water heat pump system, especially in cooling mode. It allows for an improvement in its efficiency compared to the current state of the art.

It enters through the third passage of the valve and is conveyed to the plate heat exchanger via the fourth passage. The refrigerant exiting the plate heat exchanger enters through the second path of the four-way valve and passes through the first 25 The refrigerant is conveyed to the refrigerant diffuser via this path, thus operating in cooling mode. Cross-flow formation is achieved on the plate heat exchanger. In this application, numerous Instead of using a two-way valve or two three-way valves, just one four-way valve. Its use allows for both further improvement of structural simplicity and a low number of components. When considered, this allows for a reduction in costs. 30 5 In one application of the invention, the steering group connects a primary inlet of a plate heat exchanger to a guide rail.

In the outdoor unit (9), the high-pressure hot refrigerant in gas phase coming out of the compressor (2) 30 The fluid coolant diverter (3) has changed direction according to the heating mode 9 For this reason, it is sent to a finned tube heat exchanger (6) instead of a plate heat exchanger (4). By passing outside air through the finned tube heat exchanger (6) preferably by means of a fan Heat transfer occurs between the refrigerant and the air. Following this, the refrigerant... The coolant in the liquid phase goes to the electronic tank (6). The pressure is reduced by passing through the expansion valve (5) and then inside the plate heat exchanger (4) 5 The water undergoing the cycle in unit (15) evaporates by transferring heat. The water, which transfers its heat to the coolant, cools down and the cooled water goes to the heater (11). However, the heater (11) is not working because the system (1) is in cooling mode. The water, the water Water directing system (14) which directs water to tank (12) or fan coil (13) (1) Since it is in cooling mode, it directs the water directly to the fan coil (13) position 10 In this mode, cold water is used solely for cooling the environment. Since the water for use is generally required to be hot, the temperature value in the water tank (12) The system (1) can automatically switch itself to heating mode.

It is possible. In one application of the invention, the guiding group (16), refrigerant guide (3) a first two-way valve (17) arranged between the plate heat exchanger (4), a second two 5 two-way valve (18), a third two-way valve (19) and a fourth two-way valve (20) It includes.

With the plate heat exchanger (4) the liquid 10 The coolant flow direction between the tank (7) is via the third two-way valve (19) and This is done via the fourth two-way valve (20). This application is one In the example, the air-to-water heat pump system (1) is operating in heating mode, the first two two-way valve (17) and fourth two-way valve (20) allow the coolant to pass through As they come into position, the second two-way valve (18) and the third two-way valve (19) coolant 15 Plate heat exchanger in heating mode by being placed in a position that does not allow fluid to pass through.

In one application of the invention, the guiding group (16), refrigerant guide (3) a first three-way valve (21) and a second three-way valve arranged between the plate heat exchanger (4) It includes a way valve (22). In this application, the air to water heat pump system (1) 11 Depending on whether it is in heating or cooling mode, the coolant comes out of the director (3). Coolant exits the liquid tank (7) through the first three-way valve (21).

This application's first three-way the valve (21) and the second three-way valve (22) are connected to the paths shown as A, B, C in the figures. In one example, an air-to-water heat pump system (1) in heating mode While operating, the A and C paths of the first three-way valve (21) allow the coolant to pass through. As they come into position, path B prevents the coolant from passing through. The A and B pathways of the second three-way valve (22) are brought to the position where the coolant flows.
