Abstract

The invention belongs to the field of air conditioning and energy saving related equipment and discloses a jet throttling independent temperature and humidity control air conditioning system comprising a compressor, an outdoor unit condenser, a liquid-gas ejector, a gas-liquid separator, a gas-liquid mixer, a throttling mechanism, a cooling evaporator, a dehumidification evaporator, an indoor unitfan and the like. The ejector and other assemblies are introduced to recover pressure energy of high-pressure refrigerant liquid, thus a refrigeration system can work under two different evaporationpressures, and independent temperature and humidity control of the air conditioning system is achieved. Meanwhile, a low-pressure evaporator has low evaporation temperature, and a dehumidification function of the air conditioning system is borne in a condensation dehumidification mode; and a high-pressure evaporator has high evaporation temperature and mainly bears an air cooling function of the air conditioning system. Through the jet throttling independent temperature and humidity control air conditioning system, independent temperature and humidity control of air can be achieved, air suction pressure of the compressor is also improved, energy consumption of the compressor is lowered, and the jet throttling independent temperature and humidity control air conditioning system has a higherperformance coefficient than a traditional air conditioning system.

Description

technical field [0001] The invention belongs to the field of air conditioning and energy-saving related equipment, and more specifically relates to a temperature-humidity independent control air-conditioning system with jet throttling. Background technique [0002] Air conditioning systems are widely used in various air conditioning occasions. The traditional air conditioning system generally has the function of cooling and dehumidifying the air under the cooling conditions in summer, but the refrigeration system of the traditional air conditioner usually only has one evaporator, that is to say, the evaporator of the traditional air conditioner undertakes the function of cooling the air. The function also assumes the role of air dehumidification. The evaporator achieves the purpose of dehumidification by cooling the air below the dew point temperature. Generally, the air dew point temperature in rooms that meet the thermal comfort requirements of the human body is relativel...
