[0002] Chinese patent application number 200310100992.7, publication number CN1536287A, open date October 13, 2004 or Chinese patent number CN200320101124.6, open number CN2771763, open date April 12, 2006, the name of the invention is: multi-purpose refrigeration heating air conditioner The device consists of a multi-way reversing valve composed of one or more four-way reversing valves, multiple cut-off throttle valves, multiple heat exchangers, liquid splitters, compressors, and vapor-liquid separators. Through one or more four-way reversing valves, all condensed gas is reversing to realize the transformation of various cooling and heating states. Most of the embodiments are related to heat recovery and hot water heating, and can also provide indoor heating. , this device has more outstanding advantages than other similar products in actual application, but there are still imperfections in the technical solution. The main shortcomings are: 1. Due to the use of multiple cut-off throttle valves, each unit The throttling amount is not exactly the same, and it is difficult to master in manufacturing and application; 2. Heating cannot make hot water at the same time, and when the hot water used for making hot water is greater than 55°C, the compressor current is larger than the normal working condition, and the cooling capacity is lower. The normal state declines, so that the comprehensive energy efficiency ratio decreases greatly
