Abstract
The utility model discloses a heat recovery device of a semi-enclosed screw cold water machine set. The heat recovery device comprises a compressor which is connected with a condenser, a drying filter, a heat power expansion valve and an evaporator sequentially through pipelines, and is characterized in that a heat regenerator is connected between the compressor and the condenser. The heat regenerator is mounted between the compressor and the condenser for recovering heat quantity generated through heat exchange during the operation process of the cold water machine set; and the recovered heat can be used for other purpose, thereby avoiding heat loss, and at the same time reducing work load of the condenser, and saving electric energy.
Description
Technical field
The utility model relates to a kind of heat reclaim unit, specifically relates to a kind of semiclosed screw chiller group heat reclamation device.
Background technology
At present, handpiece Water Chilling Units in the course of the work, be pressed into condenser by the high-temperature high-pressure refrigerant steam that compressor is discharged and carry out heat exchange, take heat in the cooling tower heat is discharged into the atmosphere mode by water circulating pump again, discharge the heat that brings in the heat exchanging process.The mode of this release heat can cause the waste of a large amount of heat energy, also can cause bad influence to surrounding environment simultaneously.And high-temperature high-pressure refrigerant steam directly is pressed in the condenser, strengthened the live load of condenser, expends a large amount of electric energy.
The utility model content
Problem to be solved in the utility model provides a kind of semiclosed screw chiller group heat reclamation device, to solve a large amount of heat energy of waste and the OL problem of condenser working in the handpiece Water Chilling Units course of work.
For addressing the above problem, the technical scheme that the utility model adopted is: semiclosed screw chiller group heat reclamation device, comprise compressor, compressor is connected with condenser, device for drying and filtering, heating power expansion valve and evaporimeter in turn by pipeline, it is characterized in that: be connected with heat regenerator between described compressor and the condenser.
As a kind of prioritization scheme:
Described heat regenerator is a case tube-type thermal recovery machine.
This heat regenerator structure is simpler, and operation is reliable, can under high temperature, high pressure, use, and be one of most widely used in the market type.
The utility model is by being connected heat regenerator between compressor and the condenser, reclaim handpiece Water Chilling Units in the course of the work by the heat that heat exchange brought, again the heat of retrieving is used in other purposes, prevent thermal loss, reduce the live load of condenser simultaneously, saved electric energy.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model embodiment.
Among the figure: the 1-compressor; The 2-heat regenerator; The 3-condenser; The 4-device for drying and filtering, the 5-heating power expansion valve; The 6-evaporimeter.
The specific embodiment
Embodiment: as shown in the figure, semiclosed screw chiller group heat reclamation device, comprise compressor 1, compressor 1 is connected with condenser 3, device for drying and filtering 4, heating power expansion valve 5 and evaporimeter 6 in turn by pipeline, is connected with heat regenerator 2 between described compressor 1 and the condenser 3.
Heat regenerator 2 is a case tube-type thermal recovery machine, and the shell-and-tube heat regenerator claims tubular heat exchanger again, is to be enclosed in the wall of restraining in the housing dividing wall type heat exchanger as heat-transfer area.This tubular heat exchanger is sell goods on the market, and structure is simpler, and operation is reliable, can use under high temperature, high pressure, is present most widely used type.
Case tube-type thermal recovery machine 2 can deliver a child hot water tube system alive and domestic hot-water's water tank heat the domestic hot-water, and life hot water being provided at any time.
Claims (2)
