Abstract

The invention discloses a frequency control method and system for an electric frequency conversion heat pump hot water machine compressor. The method includes the steps that the outlet water temperature of a heat exchanger and the water tank temperature of a water tank are detected; the set temperature of the outlet water of the heat exchanger is generated according to the temperature of the water tank; control over the frequency of the frequency conversion compressor is conducted according to the outlet water temperature and the set outlet water temperature of the heat exchanger. According to the frequency control method and system of the frequency conversion heat pump hot water machine compressor, the mode that control over the frequency of the compressor through the outlet water temperature of the heat exchanger is provided, the operation frequency of the frequency conversion compressor can be lowered effectively, the unit operation energy efficiency is improved, and the reliability of the compressor is guaranteed on the condition that the outlet water temperature is constant is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a frequency control method and system for a frequency conversion heat pump water heater compressor. Background technique [0002] As a high-efficiency, energy-saving and environmentally-friendly equipment, heat pump water heaters have been increasingly widely used at home and abroad in recent years. With the development of frequency conversion technology, frequency conversion heat pump water heaters have emerged. Compared with fixed-frequency heat pump water heaters, variable frequency heat pump water heaters have the advantages of large heating capacity and high energy efficiency, especially in low-temperature ambient temperatures. [0003] At present, the frequency control method adopted by the frequency conversion heat pump water heater compressor is to use the difference between the target temperature of the water tank and the instant temperature of the water...
