Heating and cooling air conditioner heat recovery device and air conditioner heat recovery system

Abstract

The invention relates to a heating and cooling air conditioner heat recovery device, which is used for recovering heat energy generated during the operation of a heating and cooling air conditioner so as to heat water. The heating and cooling air conditioner heat recovery device is provided to improve the energy efficiency of heating the water by the heat recovery of the heating and cooling air conditioner and realize a plurality of states such as independent cooling, independent heating, independent water heating, the combination of the three functions, and the like, wherein a first water heat exchanger for heating the water is connected between an exhaust port of a compressor and an input port of a multi-port reversing valve; and an independent water heat exchanging branch is also connected between another reversing port of the multi-port reversing valve and a stop-throttle valve component. The invention also provides an air conditioner heat recovery system consisting of the heating and cooling air conditioner heat recovery device and bearing / guiding water.

Description

[0001] This application is a divisional application, the application number of the original application is 200610121939.9, the application date is August 26, 2006, and the name of the invention is a multi-purpose refrigeration and heating air-conditioning device and a double heat recovery device composed of it. technical field [0002] The invention relates to a heat recovery device for cooling and heating air conditioners and a heat recovery system for air conditioning, wherein the heat recovery device for cooling and heating air conditioners is used to recover the heat energy generated during the operation of the cooling and heating air conditioner for heating water, and the heat recovery system for air conditioning is used for cooling A system composed of a heating and air conditioning heat recovery device combined with carrying / guiding water.

[0003] Chinese patent application number 200310100992.7, publication number CN1536287A, open date October 13, 2004 or Chinese patent number 200320101124.6, publication 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, vapor-liquid separators, etc., which pass through a Or a plurality of four-way reversing valves can reversing all condensed gases 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. Compared with other products of the same type, the device has more prominent advantages 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, the throttling amount of each unit Not exactly the same, 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 to make hot water is greater than 55°C, the current of the compressor is higher than the normal working condition, and the cooling capacity is higher than the normal state Decrease, so that the comprehensive energy efficiency ratio drops greatly
