공기열과 태양열을 순차적으로 이용한 히트펌프시스템{omitted}Heat pump system using air heat and solar heat in succession {omitted}

Especially in the winter, the above problems are particularly serious. The present invention aims to solve the above problems by using air heat and then solar heat in the heat pump system. First, the method of using air heat is to enclose the evaporator with water and send the enclosed water to the air heat exchanger.Then, by forced ventilation or natural heat exchange with the air, the heat-exchanged water is sent to the hot water tank containing the heat of the solar water heater in a tubular form. In a tank, the tube containing the air-heat exchanged water is wound in a circular shape, and the tube is turned to exchange water and heat exchanged therein. Then, the tube is placed in a container containing water surrounding the heat pump evaporator to take heat from the evaporator to the compressor. It is a heat pump system driven by compression. The water is pushed into the pump in the pipe to move it, but the water surrounding the evaporator is pushed into the pipe to enter the air heat exchanger, and the air heat exchanged water is put into the solar hot water tank through the pipe. Hot water in the process of turning pipes MSB will go into heat exchange takes the greater surrounding the evaporator through the pipe again. This will help you overcome the limitations of midwinter with only air heat. In addition, the installation cost is cheaper than geothermal. Geothermal heat is a source of heat at the same temperature, but at a high cost in the drilling process. The solar water heater system is relatively inexpensive. When water loses heat from the evaporator, the temperature of the water drops rapidly, exchanges the temperature of the water with air heat, raises the temperature, and then receives some heat from the solar hot water tank and enters the barrel surrounding the evaporator. Heat exchange in solar hot water tanks should be done as above, but do not try to overheat. This is because the heat in the tank quickly cools down. The solar hot water tank cannot be used for heating when it is lowered below 40C in the winter, but it can be used as an auxiliary heat exchanger in the heat pump and as a result, it can be used for heating.
