Abstract

The invention discloses an absorption-type heating and cooling air-conditioning system and its operating mode with gas-liquid separation and injection efficiency enhancement. , absorber, solution pump, solution heat exchanger, solution valve, steam injector, supersonic nozzle and control valve; One end of the pipe communicates with the second valve port of the four-way reversing valve, and the other end communicates with the first gas-liquid separator, the throttling mechanism, the second gas-liquid separator, the outdoor coil and the fourth valve of the four-way reversing valve in sequence. The third valve port of the four-way reversing valve is connected to the inlet of the lower end of the absorber; the present invention switches the flow direction of refrigerant water through the four-way reversing valve to realize the function of the heating and cooling air conditioner; The liquid phase is separated, and the steam ejector ejects the low-pressure water vapor in the gas-liquid separator, which increases the available energy entering the generator to drive the steam.

Description

Technical field [0001] The invention relates to an air-conditioning system, in particular to an absorption cooling-heating air-conditioning system with gas-liquid separation and injection efficiency enhancement and an operation mode. Background technique [0002] With the rapid development of the world economy, the environment has been greatly damaged, and the energy shortage problem has become more and more serious. Traditional compression refrigeration consumes nearly 30% of the total energy used by humans, and the refrigerant used in compression refrigeration is serious Destroyed the ozone layer. Compared with compression refrigeration, absorption refrigeration uses naturally occurring water or ammonia as the refrigerant, which is harmless to the environment and the atmospheric ozone layer. Absorption refrigeration uses certain working fluid pairs with special properties, through the absorption and release of one substance to another, resulting in a change in the state of the...
