Description
Technical field
The present invention relates to the Condensation Heat Recovery Technology field of air-conditioning, specifically a kind of reclaiming system for condensation heat of accurate temperature controlling.
Background technology
At present, the requirement of room air conditioner to comfort level is more and more higher, and in room, the control of air-conditioning accurate temperature and humid control are generally adopt converter technique, regulate the output of refrigerating capacity to control room humiture by the rotating speed changing compressor.Adopt converter technique must possess following condition: 1) must frequency-changeable compressor be adopted; 2) VFC driver etc. must be adopted, product cost is so not only made greatly to improve, and the difficulty also corresponding raising controlled, and the problem of electromagnetic interference may be there is, refrigerant flow rates particularly in compressor low-speed running process in pipeline reduces, make compressor and freeze oil cannot get back to compressor oil sump, this has higher requirement to the development process of whole convertible frequency air-conditioner.
In room air conditioner (Direct Evaporation System) field, the object controlled to reach accurate temperature generally all adopts frequency-changeable compressor, and compressor is carried out to the adjustment of rotating speed on controlling, to reach the object regulating refrigerating capacity to export, but it is very complicated that such refrigeration system controls, and easily there is the integrity problem of electromagnetic interference, cannot control effectively to relative humidity, cost is higher.If employing invariable frequency compressor, when room temperature reaches design temperature, compressor shutdown; during etc. room temperature higher than design temperature, compressor is restarted, and so circulates; but in start/stop of compressor process, room temperature there will be larger fluctuation, room air conditioner degree of comfort decreased.
Summary of the invention
The object of this invention is to provide a kind of reclaiming system for condensation heat of accurate temperature controlling, by increasing by one group of electronic three-way valve and one group of recuperation of heat finned heat exchanger, under the prerequisite improving refrigeration performance, accurate temperature control and humid control being carried out to room.
Technical scheme of the present invention is as follows:
A kind of reclaiming system for condensation heat of accurate temperature controlling, include finned evaporator, gas-liquid separator, compressor, oil eliminator, finned cooler, electronic three-way valve, reservoir, electric expansion valve and heat recovering heat exchanger, it is characterized in that: after the port of export of described finned evaporator connects described gas-liquid separator, compressor and oil eliminator successively, be divided into two tunnels, wherein the entrance point of described finned cooler is accessed on a road, and another road is connected with described heat recovering heat exchanger; The port of export of described finned cooler is connected with the entrance point of described electronic three-way valve, a port of export of described electronic three-way valve is connected with described heat recovering heat exchanger, accesses the entrance point of described finned evaporator after another port of export of electronic three-way valve connects described reservoir and electric expansion valve successively.
The reclaiming system for condensation heat of described accurate temperature controlling, is characterized in that: the rear wind path of described heat recovering heat exchanger is provided with centrifugal blower.
The present invention mainly adopts one group of triple valve and one group of heat recovery heat exchanger, heat recovery heat exchanger is arranged on before the evaporimeter of indoor, during refrigeration, system is normally run, when room temperature reaches design temperature, general frequency machine of determining just is shut down, during etc. room temperature higher than design temperature, compressor is restarted, circulation like this, but in start/stop of compressor process, room temperature there will be larger fluctuation, but in such systems, when running into this situation, compressor is not shut down, when temperature is lower than design temperature, electronic three-way valve is opened, heat recovering heat exchanger (in indoor) is entered by the part high-temperature high-pressure refrigerant gas of condenser, evaporimeter air-out is heated, it is electrodeless adjustment that the aperture of electronic three-way valve regulates, aperture size decides according to the difference of design temperature and room environment temperature, when the difference of design temperature and room environment temperature increases, aperture just increases, when the difference of design temperature and room environment temperature reduces, the aperture of electronic three-way valve reduces, until environment temperature reaches design temperature, when needs accurately control indoor environment humidity, electronic three-way valve aperture increases aperture and heats until relative humidity reaches requirement evaporimeter air-out.
Beneficial effect of the present invention:
The present invention has and differs from the general accurate temperature carrying out room by converter technique and control and humid control, by increasing by one group of electronic three-way valve and one group of recuperation of heat finned heat exchanger, under the prerequisite improving refrigeration performance, accurate temperature control and humid control are carried out to room, not only can carry out accurate temperature control and humid control, and more energy-conservation than common air-conditioning system.Wherein:
1, when freezing, compressor is not shut down all the time, when environment temperature is lower than design temperature, carries out condensing units, heats air-out, until reach required environment temperature;
2, when freezing, absorb unnecessary cold by heat recovering heat exchanger, unit condensation temperature significantly reduces, and Energy Efficiency Ratio can significantly promote.
