Temperature and humidify independent control air conditioning system with compactness and high performance

Abstract

The invention belongs to the field of air conditioning and energy-saving related equipment, and discloses a temperature and humidify independent control air conditioning system with compactness and high performance. The system comprises a compressor, an outdoor unit condenser, a liquid-air sprayer, a cooling evaporator, an air-liquid separator, a throttling mechanism, a dehumidifying evaporator and the like, wherein the pressure energy of high-pressure refrigerant liquid is recovered through introduction of such modules as the sprayer, so that a refrigerating system can work at two different evaporation temperatures; specific connecting modes of key modules are further optimally designed to greatly simplify the whole structure correspondingly; an additional air-liquid separator is not needed, the air sucking pressure of the compressor is improved, and the energy consumption of the compressor is reduced, so that the system achieves higher circulating performance and reliability; and inaddition, such aspects as condensed water collection and utilization of the evaporator and solar photovoltaic driving are transformed and upgraded.

Description

technical field [0001] The invention belongs to the field of air conditioning and energy-saving related equipment, and more specifically relates to a compact and high-performance temperature and humidity independent control air conditioning system. 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...

Problems solved by technology

[0004] With further in-depth research, the above-mentioned temperature and humidity independent control system based on jet throttling still has the following deficiencies or areas to be improved: one, it must use multiple gas-liquid separators and gas-liquid mixers and other components , which not only makes the overall structure more complex, but also greatly increases the cost of system manufacturing and maintenance; second, the energy efficiency level of the system needs to be further improved, especially it is necessary to make a targeted transformation design for its application range, and then more Efficiently realize the cooling and dehumidification function and improve the performance coefficient of the air conditioning system
