Problems solved by technology

[0002] At present, swimming pool air-conditioning consumes a lot of energy, so various new air-conditioning systems have emerged to solve the problem of increased power consumption
The air source heat pump air conditioning system and the water source heat pump air conditioning system are the most used at present, but there are some problems in these two air conditioning system technologies. If the outside temperature of the air source heat pump air conditioning system is lower than 5°C, the surface temperature of the heat transfer tube is lower than 0°C , the moisture in the air will condense into frost on the surface of the heat transfer tube. As the frost thickens, it will block the air flow channel and significantly reduce the heat absorbed by the heat pump working fluid from the air through the evaporator, resulting in air source heat pump reduction in heating coefficient and reliability of operation
Air source heat pumps need regular defrosting, which not only consumes a lot of energy but also affects the normal operation of the air conditioning system
When the air source heat pump air conditioner is cooling in summer, the condensing temperature is higher with the increase of the outdoor ambient temperature, and the refrigeration coefficient will decrease accordingly, and the energy efficiency is relatively low, which is 50% lower than the cooling coefficient of the water-cooled chiller; The freezing point of the water source heat pump air-conditioning system is 0°C. In order to ensure that the exchanger will not freeze, and to ensure the safety of the equipment, the water inlet temperature must be above 8°C in winter before it can be used. Moreover, the water source heat pump air-conditioning system needs to lay a large number of pipes underground during installation, so the cost is still low. At the same time, the heating load required in winter and the cooling load required in summer in most areas are unbalanced. The cooling load in the south far exceeds the heating load, and the heating load in the north is much greater than the cooling load. The cooling and heating loads are unbalanced. One year, the buried pipe water source heat pump will eventually cause the underground temperature of the southern project to become higher and higher, and the heat dissipation will deteriorate, causing the energy efficiency ratio of the water source heat pump in this area to gradually decrease when summer cooling is most needed, and the underground temperature of the northern project will become more and more Low heat absorption becomes worse, causing the energy efficiency ratio of water source heat pumps in this area to gradually decrease when heating in winter is most needed. As the years go by, this costly energy-saving system may eventually be paralyzed, and there is also a danger of geological variation

Abstract

An ice source heat pump system of a swimming pool comprises an ice source heat pump device and a combined type air conditioner special for the swimming pool. The ice source heat pump device comprises an air exchanger, a primary exchanger and a secondary exchanger. A hot water outlet of the secondary exchanger is communicated with a refrigerant inlet of the combined type air conditioner special for the swimming pool. A refrigerant return opening of the combined type air conditioner special for the swimming pool is communicated with a water return opening of the secondary exchanger. The ice source heat pump system has the advantages of being compact in structure and low in cost; refrigerant media which cannot be frozen at the temperature of -30 DEG C are subjected to heat exchange with air and serve as a refrigerating medium or a heating medium; a refrigerant is provided for the combined type air conditioner special for the swimming pool after heat exchange of a refrigerating agent of the exchangers; and the ice source heat pump system can adapt to the frigid weather environment, the manufacturing cost of a heat pump air conditioner system is reduced, and meanwhile the ice source heat pump system can adapt to various places.
