Abstract

The invention discloses a household air conditioner refrigerating system capable of separately controlling latent heat and sensible heat. The household air conditioner refrigerating system comprises a double-cylinder compressor, two liquid reservoirs, two evaporators, two electronic expansion valves, a condenser, an indoor fan and an outdoor fan, wherein the double-cylinder compressor is respectively provided with an air exhaust port and two air suction ports; two air suction ports of the double-cylinder compressor are respectively connected with the two liquid reservoirs; the air suction ends of the two liquid reservoirs are respectively connected with one ends of the two evaporators; the other ends of the two evaporators are respectively connected with one end of the condenser through the two electronic expansion valves; the other end of the condenser is connected with the air exhaust port of the double-cylinder compressor; the indoor fan is arranged at the side close to the two evaporators; the outdoor fan is arranged at the side of the condenser. According to the household air conditioner refrigerating system, the disadvantages of the traditional commercial temperature-humidity independent control air conditioning system are overcome; the household air conditioner refrigerating system is simple in equipment and achieves the purpose of dehumidification and temperature reduction without adding special dehumidifying equipment, the energy consumption for system operation is effectively reduced, and the indoor comfortableness and air quality are improved.

Description

technical field [0001] The invention relates to a household air-conditioning refrigeration system controlled by latent heat and sensible heat separation. Background technique [0002] At present, the temperature and humidity of most household air-conditioning systems are controlled uniformly, so there are the following problems: [0003] (1) There is a waste of energy in the heat-moisture joint treatment. Since the indoor residual humidity is removed by condensation and dehumidification, the surface temperature of the evaporator needs to be lower than the dew point temperature of the indoor air. Considering the temperature difference between heat transfer and medium delivery, if the dew point temperature of 16.6oC is achieved, the evaporation temperature below about 7oC is required. Therefore, in order to achieve the purpose of dehumidification, the evaporation temperature should be reduced as much as possible, but for the compressor, the pressure ratio increases, the input...

AI Technical Summary

Problems solved by technology

Therefore, in order to achieve the purpose of dehumidification, the evaporation temperature should be reduced as much as possible. For the compressor, the pressure ratio increases, the input force increases, and the operation is uneconomical.

[0004] (2) Difficult to adapt to changes in heat-humidity ratio

Usually the indoor heat-humidity ratio changes in a large range. By reducing the evaporation temperature, the indoor humidity is reduced, and the response of the air conditioning system is slow. At the same time, the indoor temperature after cooling is often low, and the indoor comfort is poor.

[0005] At the same time, the commercial air-conditioning system with rotary dehumidification mode is not suitable as a home air-conditioning system. The temperature and humidity of the air-conditioning system in the rotary dehumidification mode are independently controlled, and the dehumidification mode is adopted. Due to factors such as equipment and cost, commercial air-conditioning systems are used in residential air-conditioning systems. not economically viable
