Abstract
Provided is an air source heat pump hot water unit. One end of a four-way change valve is connected with a sleeve heat exchanger connected with a bidirectional liquid storage device which is connected with a bidirectional drying filter. The bidirectional drying filter is connected with a thermostatic expansion valve and a capillary tube which are connected in parallel, the thermostatic expansion valve and the capillary tube which are connected in parallel are connected with a fin heat exchanger connected with the another end of the four-way change valve, and other two ends of the four-way change valve are respectively connected with a compressor and a gas-liquid separator to form a loop. The air source heat pump hot water unit has the advantages of being capable of rapidly finishing working switch of a heating mode and a defrosting mode, solving the problem that system valves are overmany because a plurality of one-way valves are required to be arranged in the air source heat pump hot water unit, and reducing initial investment and maintenance cost.
Description
Technical field
The utility model relates to a kind of heat-pump hot-water unit, relates in particular to a kind of air-source heat pump hot water group.
Background technology
Existing air-source heat pump hot water group generally has two kinds of mode of operations; Be heating mode and defrosting mode; Unit will be accomplished the switching of two kinds of mode of operations, mostly a plurality of check valves and other system parts need be set in system, causes system pipeline loaded down with trivial details.
Summary of the invention
The purpose of the utility model is to provide a kind of air-source heat pump hot water group; Adopt capillary, heating power expansion valve, two-way device for drying and filtering, two-way reservoir, four-way change-over valve; The effective loaded down with trivial details problem of resolution system pipeline; And reduced the use amount of valve member, reduced investment of equipment and maintenance cost.
The utility model is realized like this; It comprises compressor, four-way change-over valve, gas-liquid separator, double-tube heat exchanger, two-way reservoir, two-way device for drying and filtering, check valve, heating power expansion valve, capillary, blower fan, finned heat exchanger; An end joint sleeve heat exchanger that it is characterized in that four-way change-over valve; Double-tube heat exchanger connects two-way reservoir; Two-way reservoir connects two-way device for drying and filtering, and two-way device for drying and filtering connects the heating power expansion valve and the capillary of parallel connection, and the heating power expansion valve after the parallel connection is connected finned heat exchanger with capillary; Finned heat exchanger connects the other end of four-way change-over valve, and two other port of four-way change-over valve connects compressor respectively and gas-liquid separator forms the loop.
The technique effect of the utility model is: the work that can comparatively promptly accomplish heating mode and defrosting mode is switched; And solved in the air-source heat pump hot water group a plurality of check valves need be set; The problem that system's valve member is too much has reduced investment of equipment and maintenance cost.
