Noise reduction type air energy heat-pump water heater

Abstract

Disclosed is a noise reduction type air energy heat-pump water heater. The noise reduction type air energy heat-pump water heater comprises a shell. A heat pump cycle system comprises a compressor, fin type heat exchangers, a four-way reversing valve, direct current draught fans, a condenser, and a fitting pipe which is connected with the compressor, the fin type heat exchangers, the four-way reversing valve, the direct current draught fans, and the condenser. The direct current draught fans are horizontally arranged on the top end of the heat pump cycle system, the four direct current draughtfans are uniformly distributed at the top end of the heat pump cycle system, the fin type heat exchangers are arranged on the two sides of the shell, and the compressor is fixed on the bottom plate of the upper portion by screws. By setting an alternating current draught fan, noise of the water heater is reduced, and the efficacy of noise reduction is achieved; further, a noise enclosure is arranged on the periphery of the compressor, noise caused by the compressor is separated by the noise enclosure, so that the efficacy of noise reduction is achieved.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a noise-reducing air-energy heat pump water heater with independent power supply. Background technique [0002] At present, existing heat pump water heaters mainly include a compressor, a fan, and a finned heat exchanger. Because the compressor produces low-frequency noise when it is working, the low-frequency noise has the disadvantages of strong penetration, strong vibration, and slow down; in addition, the fan also produces a certain amount of noise when it is working, and the structure of the existing heat pump water heater The noise reduction effect is not ideal, which affects the use effect of the product. Contents of the invention [0003] The object of the present invention is to provide a noise-reducing air-energy heat pump water heater capable of reducing noise in view of the deficiencies in the prior art. [0004] The object of the present invention...
