SYSTEM This invention is a 5-bit device capable of performing water heating and ambient cooling functions simultaneously. It is related to air-to-water heat pump systems. 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 In air-to-water heat pump systems operating in the known state of the art, the system Cooling cannot be performed while in heating mode. In other words, the system... While water heating is achieved through this method, ambient cooling cannot be achieved, or Water cannot be heated while ambient cooling is being performed. There are 25 known methods for addressing this deficiency in the technique. There are two different solutions to this problem. In the first solution, the system uses an algorithm. The first step is to make a decision so that heating will occur, and then the cooling process will follow with heating. This is done after the process is completed. In the second solution, heating and The order of cooling processes is determined by the user. In both solutions... Since the first operation must be completed before the second operation can be carried out, the 30th operation will be performed later. There is a performance loss and waiting time in the process. In other words, the user is experiencing water heating problems. 2 to perform the operation, either by cooling the environment or by heating water to cool the environment It has to be relinquished.
