Description
Technical field
This utility model relates to the Condensation Heat Recovery Technology field of air-conditioning, the heat high efficiente callback device of a kind of air source handpiece Water Chilling Units.
Background technology
The heat recovery of air source handpiece Water Chilling Units, as the design of domestic hot-water's thermal source, the most progressively develops to normalization.Along with country's attention to air source handpiece Water Chilling Units energy efficiency of equipment, industry starts the condensation heat of air source handpiece Water Chilling Units is carried out Recycle network.When the condensation heat of air source handpiece Water Chilling Units is reclaimed, the way that industry is general is: a water-refrigerant heat exchanger of connecting between exhaust outlet of compressor to condenser (is referred to as heat recovering heat exchanger) afterwards, from the high-temperature high-pressure refrigerant of compressor discharge after carrying out heat exchange with the domestic hot-water heat recovering heat exchanger, a part of condensation heat enters back into train condenser continuation heat exchange and carries out kind of refrigeration cycle after being absorbed by domestic hot-water, and domestic hot-water is supplied to user and uses after being heated up.System condensing temperature is at zone of reasonableness can effective heating domestic hot water to use this blood circulation to also ensure that in the case of ambient temperature is higher, if but at low ambient temperatures, when producing domestic hot-water, condensation temperature can reduce quickly, the compression ratio causing compressor is too low and causes the system failure, simultaneously because condensing pressure is too low and makes condensing units deterioration of efficiency.
Utility model content
The purpose of this utility model is to provide the heat high efficiente callback device of a kind of air source handpiece Water Chilling Units, it is possible not only to the situation effectively preventing refrigeration system condensing pressure too low, and the efficiency of condensing units can also be effectively improved, additionally use this utility model as the thermal source of domestic hot-water, can effectively prevent condensation temperature while recovering condensing heat produces domestic hot-water from reducing the problem that amplitude is excessive.
The technical solution of the utility model is as follows:
A kind of heat high efficiente callback device of air source handpiece Water Chilling Units, include compressor, heat recovering heat exchanger, three-way solenoid valve, check valve, first, second condenser, reservoir, expansion valve, vaporizer and gas-liquid separator, it is characterized in that: after the port of export of described compressor is connected with the entrance point of described heat recovering heat exchanger, it is connected with the entrance point of described three-way solenoid valve, two ports of export of described three-way solenoid valve are respectively with described first, the entrance point of the second condenser is connected, described check valve is connected to described first, between the entrance point of the second condenser, described first, the port of export of the second condenser is in parallel and is sequentially connected with described reservoir, expansion valve, after vaporizer and gas-liquid separator, it is connected with the entrance point of described compressor.
The heat high efficiente callback device of described air source handpiece Water Chilling Units, it is characterised in that: first, second described condenser is finned cooler.
The heat high efficiente callback device of described air source handpiece Water Chilling Units, it is characterised in that: described vaporizer is plate-type evaporator.
The heat high efficiente callback device of described air source handpiece Water Chilling Units, it is characterised in that: described expansion valve is heating power expansion valve.
In air source handpiece Water Chilling Units field, the most all use Condensation Heat Recovery Technology, to obtain domestic hot-water and to improve refrigeration performance；nullAnd heat recovering heat exchanger is the most all connected on the centre of compressor air-discharging outlet and air cooling fin formula condenser，It is not necessarily in view of condensing units heating domestic hot water and uses with unit simultaneously，So finned cooler is typically by designing at full capacity，So when domestic hot-water produced by needs (namely during condensing units)，The area of finned cooler can substantially exceed the condensation load of unit，Particularly in the case of ambient temperature is relatively low，Condensing pressure so can be caused too low，When condensing pressure is reduced to a certain degree when，Can be beyond the range of operation of compressor，Unit reliability is caused to decline，Simultaneously，Decline along with condensing pressure (temperature)，The organic efficiency of heat can be greatly reduced，And this utility model can be used in the air source handpiece Water Chilling Units of all band heat recovery functions，The problem that the system reliability caused due to the great decline of condensation temperature declines can be overcome，The efficiency of condensing units can be improved again simultaneously.
This utility model mainly installs one group of three-way solenoid valve and one group of check valve additional in the middle of heat recovering heat exchanger and finned cooler, finned cooler is divided into two parts simultaneously, being first, second finned cooler, a part of heat exchange amount therein is roughly the same with the heat exchange amount of heat recovering heat exchanger.When heat recovering heat exchanger does not carry out heat exchange, two groups of finned coolers all come into operation, and when heat recovering heat exchanger carries out heat exchange (when providing domestic hot-water), make only one group finned cooler come into operation after electromagnetic three-way Vavle switching.
The beneficial effects of the utility model:
1, this utility model can carry out condensing units as other band recuperation of heat units, it is provided that domestic hot-water.
2, this utility model adds three-way solenoid valve and check valve, and finned heat exchanger is divided into two parts, when heat recovering heat exchanger works (when domestic hot-water is provided), by three-way solenoid valve and check valve effect, only one group finned heat exchanger is come into operation, refrigeration system condensing pressure is made to be unlikely to reduce excessive, it is ensured that system reliability.
3, during heat recovering heat exchanger work (when domestic hot-water is provided), by three-way solenoid valve and check valve effect, only one group finned heat exchanger is come into operation, refrigeration system condensing pressure is made to be unlikely to reduce excessive, ensure that the heat exchange efficiency of heat recovering heat exchanger, it is ensured that the temperature of domestic hot-water.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of heat high efficiente callback device of air source handpiece Water Chilling Units, include compressor 1, heat recovering heat exchanger 2, three-way solenoid valve 3, check valve 4, first, second condenser 5, 6, reservoir 7, expansion valve 8, vaporizer 9 and gas-liquid separator 10, after the port of export of compressor 1 is connected with the entrance point of heat recovering heat exchanger 2, it is connected with the entrance point of three-way solenoid valve 3, two ports of export of three-way solenoid valve 3 are respectively with first, second condenser 5, the entrance point of 6 is connected, check valve 4 is connected to first, second condenser 5, between the entrance point of 6, first, second condenser 5, the port of export of 6 is in parallel and is sequentially connected with reservoir 7, expansion valve 8, after vaporizer 9 and gas-liquid separator 10, it is connected with the entrance point of compressor 1.
