Evaporative cooling heat pump assembly

Abstract

The invention provides an evaporative cooling heat pump assembly. The other end of an evaporative cooling heat exchange unit communicates with a liquid accumulator through a third electromagnetic valve. The liquid accumulator is connected with a first expansion valve, wherein the first expansion valve is connected with the other end of indoor heat exchange through a fourth electromagnetic valve and a second electromagnetic valve. A first connector A communicates with a connecting pipeline between the other end of the evaporative cooling heat exchange unit and a third electromagnetic valve through a first electromagnetic valve, a first one-way valve and a fifth electromagnetic valve. The connecting pipeline between the other end of the evaporative cooling heat exchange unit and the third electromagnetic valve communicates with the connecting pipeline between the fourth electromagnetic valve and the second electromagnetic valve through a ninth electromagnetic valve. The first expansion valve communicates with the connecting pipeline between the first one-way valve and the fifth electromagnetic valve through a second one-way valve. The second one-way valve communicates with the connecting pipeline between the liquid accumulator and the third electromagnetic valve through a sixth electromagnetic valve. The connecting pipeline between the liquid accumulator and the third electromagnetic valve communicates with the connecting pipeline between the fourth electromagnetic valve and the second electromagnetic valve through a tenth electromagnetic valve. The evaporative cooling heat pump assembly is convenient to use, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to an evaporative cooling and heat pump unit. Background technique [0002] Among the three cooling methods of the air conditioner, to obtain the same cooling capacity, the unit using the evaporative cooling method (evaporative cooling unit) can save more than 30% energy than the air-cooled unit (the air-cooled unit includes the multi-connected unit), and it can save more than 30% compared with the water-cooled unit. The unit (water-cooled unit) saves energy by more than 15%, and the evaporative cooling efficiency is the highest. [0003] Among them, the thermodynamic cycle process of the air conditioning unit is the process of transferring cooling capacity and heat between the evaporator and the condenser, and the reverse cycle process of refrigeration is heating. The evaporative refrigeration unit only realizes cooling and cannot realize the heat pump function. [0004] The tr...

Problems solved by technology

However, its disadvantages are many components, complex pipelines, cumbersome control system, high unit function conversion frequency, resulting in poor unit stability and high failure rate. When the compressor is not fully loaded, the heat of the compressor cannot be recovered, which reduces the overall efficiency of the unit.
