High-efficiency heat pump water heater

Abstract

The invention discloses a high-efficiency heat pump water heater which is of an integral wall-mounted structure and comprises a main machine part, a condenser coil, a water tank and a housing. The main machine part comprises a compressor, an evaporator, a square shell and a fan; the compressor, the evaporator and the fan are arranged in the square shell; the main machine part is fastened on a flange face of the end face of the water tank to form one whole body to be arranged in the housing; the condenser coil is arranged in the water tank, is integrated with the main machine part into one whole body and can be installed and disassembled along with the main machine part; two insulating layers which respectively are a vacuum insulation board layer and a polyurethane foaming layer are arranged between the outer surface of the water tank and the inner surface of the housing; air inlets are formed in the end face of one end and in the lateral surface of the main machine part of the water heater; an air outlet is formed above the water heater; the fan is an aluminium alloy fan; the number of blades of the fan is an odd number; each blade has an inclination angle of 28 degrees; application of two insulating layers not only can effectively improve thermal insulation property of the water tank, but also can reduce the use quantity of polyurethane foaming materials, so that the heat pump water heater is more environmental-friendly.

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to a high-efficiency heat pump water heater. Background technique [0002] At present, the thermal insulation water tanks of heat pump water heaters on the market are basically made of polyurethane foam for thermal insulation, and its poor thermal conductivity is used to block the heat transfer from the inner tank to the outer shell. With the continuous development of heat pump water heater production technology, we need energy-saving and environmentally friendly heat pump water heaters with better thermal insulation performance. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes an energy-saving and environment-friendly high-efficiency heat pump water heater with good thermal insulation performance. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The high-efficiency heat pu...
