Embodiment Construction

[0011] see Figure 1-Figure 4 , a high-energy-efficiency air-source heat pump water heater, which includes an axial flow fan, a motor, a rotating shaft of the motor, and a compressor. The axial flow fan is composed of a hub 10 as a rotating shaft and blades, the hub 10 is installed on the rotating shaft of the motor, and the blades have Blade surface, leading edge 21a, trailing edge, blade outer edge 22, a number of blades are evenly arranged on the periphery of the hub 10, the blade surface is horizontally S-shaped, and longitudinally is a large arc, and the leading edge 21a is partially thickened and the leading edge sharp angle 21b is increased . Described blade has three.

[0012] see Figure 1-Figure 3 , the described blade surface is made up of arc surface one 23a and blade surface arc surface two 23b. The back side becomes a large arc, and the blade surface two 23a protrudes from the front of the blade to form a small arc, while the longitudinal direction of two part...

Abstract

The invention relates to an air source heat pump water heater with high energy efficiency, comprising an aerofoil fan, a motor, a motor rotation shaft and a compressor, wherein the aerofoil fan consists of a wheel hub used as a rotation shaft and a blade, wherein the wheel hub is arranged on the motor rotation shaft; the blade is provided with a blade surface, a front edge, a rear edge and an outer blade edge; a plurality of the blades are arranged on the periphery of the wheel hub uniformly; the blade surface is S shaped in a transverse direction and is a large arc in a longitudinal direction; and a part of the front edge is thickened and is additionally provided with a front edge closed angle. The invention improves the aerofoil fan, thereby meeting the requirements for silence, energy saving and high efficiency of the heat pump water heater.

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to an air source heat pump water heater with high energy efficiency. Background technique [0002] The air source heat pump water heater is designed using the reverse Carnot cycle principle, which pumps heat from a low temperature environment into a high temperature water system. According to the principle of heat conservation, to improve the performance of the unit is to increase the amount of heat absorbed from the low temperature environment as much as possible. The heat equipment that the air source heat pump water heater absorbs from the low temperature environment is generally an aluminum foil fin heat exchanger that uses an axial fan for forced convection heat exchange. Therefore, the quality of the axial fan directly affects the performance of the heat pump water heater, that is, the coefficient of performance and noise. At present, the axial flow fans on the market all have the ...
