Title:
FREQUENCY OPTIMIZATION METHOD FOR DYNAMIC HEATING COMPRESSOR OF VARIABLE FREQUENCY HEAT PUMP WATER HEATER
Document Type and Number:
WIPO Patent Application WO/2019/080277
Kind Code:
A1
Abstract:
Disclosed is a frequency optimization method for a dynamic heating compressor of a variable frequency heat pump water heater. The variable frequency heat pump water heater comprises a variable frequency compressor (1), a gas-liquid separator (2), an evaporator (3), a throttling valve (4), an outdoor environment temperature sensor (5), a controller (6), a water tank temperature sensor (7), a water tank (8), a condenser (9), a four-way valve (10) and an exhaust gas temperature sensor (11). The variable frequency heat pump water heater performs dynamic heating operation, i.e., while a user uses hot water, the heat pump water heater performs heating operation; in the entire dynamic heating process, the working frequency of the compressor (1) is optimized-adjusted; the segmented working frequencies of the compressor (1) at each temperature section are distributed in an arithmetic progression according to the segmenting condition of temperature differences of water temperature in the water tank (8), such that the total energy consumption of the heat pump water heater is minimum in the entire dynamic heating process.
