Ice source air exchanger with evaporative condenser

Abstract

The invention relates to an ice source air exchanger with an evaporative condenser. The ice source air exchanger comprises a shell, heat radiation padding and a fan. A filling chamber is filled with the heat radiation padding. The fan is fixed to an air outlet. The evaporative condenser is arranged in the position, between the fan and the filling chamber, of the shell. The inlet end of the evaporative condenser is communicated with a liquid outlet pipe of a compressor. A refrigerant output pipe is arranged at the outlet end of the evaporative condenser. An ice source solution accumulation pool is located under the filling chamber and the evaporative condenser and connected with a spray pipe through a circulating water pump. The spray pipe is arranged at the top end of the filling chamber and the top end of the evaporative condenser. A solution outlet communicated with the ice source solution accumulation pool is formed in the lower end of the filling chamber. 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, and the refrigerating or heating effect is improved; high-temperature evaporation is achieved, efficiency is improved, and energy consumption is reduced; and the ice source air exchanger can adapt to the frigid weather environment, and three functions of refrigerating, heating and domestic hot water can be provided indoors.

Problems solved by technology

Now air conditioners are basically used in every household. With the use of air conditioners, the power consumption has increased sharply. Therefore, 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 absorption of the heat pump working fluid from the air through the evaporative condenser, causing the air source Reduced heating coefficient and operational reliability of heat pumps

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; while the water source heat pump air conditioning system is due to water 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
