Problems solved by technology

The former is not widely used due to the limitation of the volume of the water tank; the latter occupies precious ground due to the use of large water tanks, and the COP value of the heat pump system is reduced due to the addition of water pumps
Both of them cannot provide hot water at any time because the water in the water tank needs to be heated for a period of time; in the period when hot water is not needed, both of them consume electricity redundantly in order to maintain the water temperature in the water tank

Abstract

The invention discloses a ready-to-use heat pump water heater. A plurality of heat pump units and evaporators (9) are arranged in the shell (3), wherein each heat pump unit comprises a refrigerating compressor (6) and a condenser (7); gas outlets of the evaporators (9) are respectively communicated with the refrigerating compressors (6), and the gas outlet of each refrigerating compressor (6) is respectively connected with the gas inlet of each condenser (7); the liquid outlet of each condenser (7) is communicated with the liquid inlet of each evaporator (9); the condensers (7) are mutually communicated after connected in series by a pipeline III (12); a clear water inlet (1) is communicated with the inlet of the first condenser (7) by a pipeline I (13), and a hot water outlet (2) is communicated with the outlet of the last condenser (7) by a pipeline II (14); and the clear water inlet (1) is communicated with the hot water outlet (2) by the mutual communication among the condensers (7).

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to an instant-on heat pump water heater. Background technique [0002] The heat pump water heater includes a heat pump circulation system. The current heat pump water heater circulation system contains a water tank for prefabricated hot water. device) to cycle through. The former is not widely used due to the limitation of the volume of the water tank; the latter occupies precious ground due to the use of a large water tank, and the COP value of the heat pump system is reduced due to the addition of water pumps. Both of them cannot provide hot water at any time because the water in the water tank needs to be heated for a period of time; in the period when hot water is not needed, both of them consume electricity excessively in order to maintain the water temperature in the water tank. Contents of the invention [0003] The invention provides an instant-on heat pump water heater, which...
