Title:
COMPRESSOR, HEAT PUMP SYSTEM, WATER HEATER AND CLOTHES DRYING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/132894
Kind Code:
A1
Abstract:
Disclosed are a compressor, a heat pump system, a water heater and a clothes drying machine. The compressor is internally provided with a first compression chamber (12) and a second compression chamber (13) for respectively compressing an inlet gas to obtain compressed gas streams of different pressures. The compressor (1) is applied to a heat pump system. The compressed gas streams of different pressures expelled by the compressor (1) each enter different condensers (2, 3), so as to obtain two different condensing temperatures, and two refrigerants having different condensing temperatures enter a same evaporator (4) after being throttled, so as to obtain a same evaporating temperature. The two different condensing temperatures allow cascading utilization of energy. The heat pump system is applicable to a water heater. Air passes through the evaporator (4) to reduce the temperature thereof. Water passes through the second condenser (2) and the first condenser (3) to incrementally increase the temperature thereof, and the total temperature increase is no more than 20ºC. The heat pump system is applicable to a clothes drying machine. The clothes drying machine generates moist gases. The moist gasses are expelled, pass through the evaporator (4) to reduce the temperature and humidity thereof, and then pass through the second and the first condensers (2, 3) to achieve a sequential temperature increase before being returned to a clothes drying cylinder (10). The invention achieves an improvement in energy efficiency of 10% or more.
