Title:
REFRIGERATION- AND HEAT ACCUMULATION METHOD AND REFRIGERATION- AND HEATING ANTI-FROST METHOD AND AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/032293
Kind Code:
A1
Abstract:
An air conditioning system, comprising a phase-change accumulator (12) wrapped around a compressor (13), the phase-change accumulator (12) having a first fluid port and a second fluid port; one end is connected to a first accumulator pipe between an expansion valve (6) on a first pipe and an outdoor heat exchanger (4), the other end of the first accumulator pipe is connected to the first fluid port, and the first accumulator pipe is serially connected to a first two-way valve (7); one end is connected, by means of a three-way valve (8), to a second accumulator pipe between the expansion valve (6) on the first pipe and an indoor heat exchanger (11), the other end of the second accumulator pipe is connected to the second fluid port, and the second accumulator pipe is also provided with a pressure sensor (9) used for measuring the pressure inside the phase-change accumulator (12). The structural design of the air conditioning system effectively regulates, according to air conditioning load conditions, the amount of refrigerant circulating in the air conditioning system. Also disclosed are a refrigeration accumulation method, a heating accumulation method, a refrigeration anti-frost method, and a heating anti-frost method, which are used for an air conditioning system.
