Air source heat pump

Abstract

The invention discloses an air source heat pump which comprises a shell, a fan, an evaporator, a compressor and an electric control element. The shell is provided with a middle partition plate for dividing an internal containing space. The fan is arranged on a fan frame on one side of the middle partition plate. The evaporator is arranged along the side wall and the rear wall of the shell, and the evaporator and the fan are located on the same side of the middle partition plate. The compressor and the electric control element are both arranged on the other side, opposite to the fan, of the middle partition plate. The air source heat pump further comprises a condenser which covers the inner bottom of the shell and penetrates through the middle partition plate, and a protection plate abutting against the middle partition plate is arranged on the condenser. According to the air source heat pump provided by the invention, the condenser is arranged at the bottom of a machine body and penetrates through a fan bin and a press bin, and on the premise that the stability of the gravity center structure of the whole machine is guaranteed, the containing space in the machine shell is fully utilized. In addition, the invention further provides the protection plate for protecting the condenser, the protection plate and the fan frame are in an assembly relationship, the stability of the machine body structure is further improved, meanwhile, noise reduction and shock absorption functions are achieved, and the air source heat pump is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the field of heat pumps, and in particular relates to an air source heat pump. The air source heat pump adopts an integrated machine structure, and the condenser is arranged at the bottom of the body, which is conducive to the stability of the whole machine and can increase the stability of the wall-mounted installation. In addition, the body also includes a guard plate that protects the condenser and is assembled with the fan frame, which not only further increases the stability of the body structure, but also has the function of reducing noise and shock. Background technique [0002] With the development of heat pump industry applications, the design of heat pump products is also diversified. For larger side air source heat pump chillers, the design is generally based on the direction of the modular unit in the early stage, and the top air is generally designed. As for the air source heat pump chillers with side air outlet, ...

Problems solved by technology

[0003] Due to the limitations of the current body structure, the air source heat pump chiller with small power and side outlet air integration generally adds a condenser (water side) on the top of the body on the basis of the existing air conditioner products, but this design will cause The center of gravity of the whole machine is too high, resulting in insufficient stability of the center of gravity of the product

In another solution of the prior art, the space of the compressor compartment in the machine body is relatively large, so the condenser (water side) is placed in the compressor compartment, but there is also the problem that the center of gravity is biased to the side of the compressor, resulting in an unstable structure Technical problems; in addition, the selection of this scheme will lead to limited selection of condensers, and only casing heat exchangers or plate heat exchangers can be selected. There is a big gap, and although the plate heat exchanger is better in heat transfer, its adaptability to complex water quality is lower, requiring higher installation conditions and higher maintenance costs
