Water vapor compressor, water vapor compressor assembly and air conditioning unit

Abstract

The invention provides a water vapor compressor, a water vapor compressor assembly and an air conditioning unit. The water vapor compressor comprises a shell, a bypass pipeline and an air inlet pipeline, the first end of the bypass pipeline communicates with an exhaust port, and the second end of the bypass pipeline communicates with an air inlet. According to the water vapor compressor, the water vapor compressor assembly and the air conditioning unit, part of exhaust gas is drained to the air inlet through the bypass pipeline, low-temperature water vapor in the air inlet is subjected to high-temperature vaporization, the pressure of the water vapor is increased, the situation that a small amount of water vapor is gathered into liquid drops due to insufficient temperature and makes contact with an impeller rotating at a high speed is avoided, the compression power consumption of the impeller can be effectively reduced, the working efficiency of the whole compressor can be fully improved, the evaporator and the condenser can adjust the temperature and pressure state of water vapor in the bypass pipeline according to needs, and therefore it is guaranteed that the water vapor compressor can work normally at any moment, and the working reliability of the compressor is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to a water vapor compressor, a water vapor compressor assembly and an air conditioning unit. Background technique [0002] As a new generation of refrigerants, water has many advantages such as being environmentally friendly (ODP=0, GWP<1), wide source of raw materials, low mining cost, high stability coefficient, and sufficient vaporization heat storage, etc., and can fully meet the environmental protection requirements of heat pump air conditioners However, as a fluid with low molecular mass, water has a large specific volume and a high adiabatic index during vaporization, which also limits the system pressure difference, bringing about the characteristics of small cooling capacity per unit volume and high exhaust temperature. Therefore, the use of water Compressors using vapor as a new generation refrigerant also have higher standards than compressors using tra...
