Embodiment Construction

[0019] figure 1 An embodiment of the present invention is given, which consists of a refrigeration compressor 1, a four-way reversing valve 2, a front-rear stage coupling heat exchanger 3, an expansion valve 4, an outdoor unit air heat exchanger 5, and a gas-liquid separator 6. stage ultra-low temperature heat pump circuit; composed of refrigeration compressor 7, compressor check valve 8, four-way reversing valve 9, liquid storage gas-liquid separator 10, refrigerant liquid pump 11, refrigerant liquid pump check valve 12, indoor unit The air heat exchangers 13, 14, 15 and the expansion valves 16, 17, 18 form a post-stage ultra-high temperature heat pump circuit.

[0020]In summer, if the temperature is lower than 30°C, the front-stage ultra-low temperature heat pump operates independently for cooling. Its working process is as follows: the exhaust gas from the refrigeration compressor 1 passes through the a-end to the d-end of the four-way reversing valve 2, and passes through...

Abstract

The invention discloses a single-double-stage complementary-type one-support-multiple wind energy heat pump air conditioner which is characterized by being composed of two stages of heat pumps including a front-stage ultralow-temperature heat pump and a rear-stage ultrahigh-temperature heat pump, and the single-stage individual operation of the front-stage ultralow-temperature heat pump or the double-stage simultaneous operation of the front-stage ultralow-temperature heat pump and the rear-stage ultrahigh-temperature heat pump is realized by front-rear-stage coupled heat exchangers and single-double-stage complementary conversion devices for the two stages of the heat pumps; and a single-double-stage complementary-type ultralow-temperature one-support-multiple wind energy air conditioning system implements single-stage refrigerating operation in summer at the temperature lower than 35 DEG C and single-stage heating warming operation in winter at the temperature of 5 DEG C above, as well as the double-stage efficient refrigerating operation in summer at the temperature higher than 35 DEG C under a hot environment and the double-stage heating operation in winter at the temperature lower than minus 5 DEG C under the cold environment, is simple and concise, is energy-saving and environment-friendly, and operates reliably and safely..

Description

technical field [0001] The invention relates to a multi-machine split air conditioner which can operate efficiently both in an ultra-low temperature environment and in a high temperature and hot environment, in particular to a single-stage and double-stage complementary one-to-multiple wind energy heat pump air conditioner. Background technique [0002] Wind energy split heat pump air conditioners, especially VRV multi-machine split frequency conversion wind energy heat pump air conditioners, are more and more widely used in household and small commercial air conditioning systems because of their advantages of simple installation and construction, less maintenance, and high load regulation rate. . However, this type of air conditioner has a common shortcoming. When the temperature is lower than 5°C, its heating operation efficiency drops significantly in proportion to the temperature drop, which makes this type of air conditioner unable to provide normal heating in winter. T...
