Abstract
A directly-heating type recycling water chilling unit comprises a compressor, a condenser, an expansion valve, an evaporator and a directly-heating recycler. An air exhaust port of the compressor is connected with the directly-heating recycler and the condenser through pipelines, a liquid exhaust port of the condenser is connected with a liquid inlet of the expansion valve through a pipeline, a liquid outlet of the expansion valve is connected with an inlet of the evaporator through a pipeline, and an outlet of the evaporator is connected with an air suction portion of the compressor through a pipeline. The directly-heating type recycling water chilling unit avoids water tanks, reduces installation cost, can directly obtain hot water for life, eliminates heat exchange through water tank circulation and is low in fault rate, convenient to maintain, free of combustion emission pollution in running processes of the unit and good in environmental protection.
Description
Technical field
The utility model relates to a kind of handpiece Water Chilling Units, specifically a kind of direct-heating-type recuperation of heat handpiece Water Chilling Units.
Background technology
At present, in common recuperation of heat handpiece Water Chilling Units industry, all be circulating recuperation of heat mode generally; The client will be cyclic water tank of handpiece Water Chilling Units heat regenerator polygamy; The domestic hot-water who needs must could obtain through the water tank heat-shift that constantly circulates, and can not settle at one go, often can not satisfy user side to producing the demand of hot water aspect fast; The water tank of joining unit simultaneously also makes the assembly cost of whole handpiece Water Chilling Units increase.
Summary of the invention
The technical problem that the utility model will solve provides the direct-heating-type recuperation of heat handpiece Water Chilling Units that a kind of assembly cost is low, can reclaim hot water fast.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of direct-heating-type recuperation of heat handpiece Water Chilling Units; Comprise compressor, condenser, expansion valve and evaporimeter; And the direct-heating-type heat regenerator, the exhaust outlet of said compressor is connected with direct-heating-type heat regenerator, condenser through pipeline, and the liquid outlet of condenser is connected with the liquid-inlet of expansion valve through pipeline; The liquid outlet of expansion valve is connected with the inlet of evaporimeter through pipeline, and the outlet of evaporimeter is connected with the air entry of compressor through pipeline.
Said direct-heating-type heat regenerator is a shell and tube exchanger.
Said condenser is plate type heat exchanger or shell and tube exchanger or finned heat exchanger or double pipe heat exchanger.
Said expansion valve is heating power expansion valve or electric expansion valve or capillary.
Said evaporimeter is plate type heat exchanger or shell and tube exchanger.
The utility model need not assemble water tank, has reduced the cost cost, and the user can obtain life fast and use hot water, and fault rate is low, maintenance convenient, and unit no burning and exhausting pollution in running, and the feature of environmental protection is good.
Description of drawings
Accompanying drawing 1 is the utility model catenation principle figure.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Shown in accompanying drawing 1; A kind of direct-heating-type recuperation of heat handpiece Water Chilling Units; Comprise compressor, condenser, expansion valve 1, evaporimeter; And the direct-heating-type heat regenerator, the exhaust outlet of the high temperature and high pressure gas of said compressor is connected with direct-heating-type heat regenerator, condenser through pipeline, and the middle temperature high pressure refrigerant liquid outlet of condenser is connected with the high pressure refrigerant liquid import of expansion valve 1 through pipeline; The liquid outlet of expansion valve 1 is connected with the middle temperature low pressure refrigerant liquid inlet of evaporimeter through pipeline, and the outlet of evaporimeter is connected with the air entry of compressor through pipeline.
In addition, the direct-heating-type heat regenerator is a shell and tube exchanger.Condenser is preferably plate type heat exchanger or shell and tube exchanger or finned heat exchanger or double pipe heat exchanger.Expansion valve is preferably heating power expansion valve or electric expansion valve or capillary.Evaporimeter is preferably plate type heat exchanger or shell and tube exchanger.
The utility model adopts the direct-heating-type heat regenerator; Compare with the traditional hot recover; Domestic water can fast directly obtain the domestic hot-water that the user wants with the healthy heat-shift of HTHP refrigerant vapor of compressor discharge, has realized the purpose of the required hot water of quick extraction, and need not be equipped with water tank and remove constantly to circulate heat-shift; Simplify installation step, saved the cost cost.
During work, the high-temperature high-pressure refrigerant steam that compressor is discharged gets into the direct-heating-type heat regenerator, and directly sufficient and domestic water carries out heat exchange, and the hot water that directly comes out is given user side; Get into condenser then after high-temperature high-pressure refrigerant steam and the domestic water heat exchange, carry out heat exchange, get into expansion valve during steam is condensed into behind the refrigerant liquid of warm high pressure again with cooling water; Through expansion valve throttling step-down is the refrigerant liquid of low-temp low-pressure, gets into evaporimeter then, the heat of absorption refrigerating water; Become the refrigerant gas of low-temp low-pressure; Get back to compressor, form a refrigerant loop, and so circulation.
