Abstract

The invention provides a multi-way reversing valve and a heat pump unit. The multi-way reversing valve comprises a shell and a shell cavity, a partition plate is further arranged in the interior of the shell to divide the shell cavity into a shell upper cavity and a shell lower cavity; a plurality of communication ports communicated with the interior of the shell upper cavity are formed in the shell upper cavity of the multi-way reversing valve, and a plurality of communication ports communicated with the interior of the shell lower cavity are formed in the shell lower cavity of the multi-wayreversing valve. The multi-way reversing valve and heat pump unit has the advantages that structure is simple, dismounting and mounting are convenient, and problems of multiple flow path valves and complicated control are solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a multi-way reversing valve and a heat pump unit. Background technique [0002] At present, water source / ground source heat pump units use source water (sources include groundwater, river water, cooling tower water, and buried pipe cooling water) as the main energy source, and turn the low-grade energy of source water into heating in winter and cooling in summer high-grade energy. Large-scale screw water source / ground source heat pump units are the main air-conditioning units for large buildings. Unlike small heat pump units, which can switch between cooling and heating modes through four-way valve switching, they generally use external pipeline switching for cooling and heating. Mode conversion. Common large screw water source / ground source heat pump units such as figure 1 As shown, the unit includes a compressor, a condenser, an evaporator, a throttling ...
