Document Type and Number:
WIPO Patent Application WO/2020/113890
Kind Code:
A1
Abstract:
The present invention relates to a machine room air conditioner heat recovery system, comprising a compressor unit, a first condenser, a throttling device and an evaporator, wherein the compressor unit and the first condenser are connected through a heat recovery circuit and a first bypass circuit arranged in parallel; a second condenser is arranged on the heat recovery circuit, the second condenser is fixedly arranged on the air inlet side of home or commercial air conditioner outdoor unit heat exchanger; the heat recovery circuit and the first bypass circuit are provided with a control valve for switching the heat recovery circuit or the first bypass circuit, to make the machine room air conditioner start or exit the heat recovery mode. The present invention uses the heat released by the second condenser to preheat the inlet air of the outdoor unit heat exchanger during heating of home or commercial air conditioner, increasing the evaporation temperature of the outdoor unit heat exchanger, so as to improve the low-temperature heating capability and heating energy efficiency ratio of home or commercial air conditioner. The present invention also provides a control method of the machine room air conditioner heat recovery system, achieving the automatic control of the machine room air conditioner heat recovery system.
