According to the invention, the branch with the heater is connected in parallel on the exhaust pipeline between the compressor and the outdoor heat exchanger, and the branch is opened when heating compensation is needed, so that a high-temperature and high-pressure refrigerant flowing out of the compressor flows through the heater to be equal to the condenser, and the heater is positioned indoors, and high-pressure and high-temperature exhaust gas is condensed inside to heat the environment, thereby realizing refrigeration and heating compensation and improving the indoor temperature.
Description
Technical field
The present invention relates to field of air conditioning more particularly to a kind of air conditioners.
Background technique
For the stable operation for meeting calculator room equipment, air conditioner in machine room needs annual uninterrupted operation, to guarantee inside computer room
Temperature, humidity remain constant.Common computer-room air conditioning system is all made of and determines frequency compression, therefore, in certain periods, in order to maintain
Certain temperature, humidity, inevitably, unit need while refrigeration, to computer room inside put into thermic load, for balancing
Excessively refrigeration bring temperature drop.Conventional scheme is to be converted into thermal energy by consumption of electric power using electric heater, to room
Temperature-compensating is realized in heating.But following ask can be brought although can be realized control target temperature using electrically heated scheme
Topic:
Using electric heater, needing to be provided separately 220V power supply, it is 3 phases electricity that air conditioner in machine room, which often uses power supply, for balance phase voltage,
It needs for electric heater to be divided into three groups to set, increases the complexity of set structure and electrical wiring, it is hidden to be easy that there are electrical safeties
Suffer from.It will increase the power of unit consumption simultaneously, reduce efficiency, the requirement with energy-saving and emission-reduction is runed counter to.
Summary of the invention
In order to solve drawbacks described above existing in the prior art, the invention proposes a kind of air conditioners.
The invention proposes a kind of air conditioners, comprising: compressor, outdoor heat exchanger and indoor heat exchanger, the compressor
A branch for the heating compensation that freezes is drawn on exhaust pipe, the branch road is equipped with positioned at indoor heater, another
One end is connected to the entrance of outdoor heat exchanger.
The exhaust pipe of the compressor is equipped with reversal valve, and the branch is connected on reversal valve.
The reversal valve is the electric change valve controlled by controller.
The pipe outlet of the branch is equipped with check valve.
The heater is wholely set with indoor heat exchanger, and is located at inlet side.
The heat exchanger tube of the heater and the heat exchanger tube of indoor heat exchanger are arranged side by side.
Heat transmission fin is equipped between the heat exchanger tube of the heater and the heat exchanger tube of indoor heat exchanger.
The heat transmission fin is Integral finned heat exchanger.
The air conditioner is machine room air conditioner.
Compared with prior art, the present invention passes through one in parallel on the exhaust pipe between compressor and outdoor heat exchanger
Branch, branch road are equipped with heater, branch are opened when needing heating compensation, and the high temperature and pressure refrigerant for flowing out compressor flows through
Heater is equal to condenser, and heater is located at interior, and the exhaust of high pressure-temperature is condensed in the inside, added to environment
Heat realizes refrigeration heating compensation, promotes room temperature, flow to outdoor heat exchanger again by the refrigerant of heater, directly take away room
The excessive refrigerating capacity of interior heat exchanger reduces refrigerating capacity, while using the cooling capacity of the part, the refrigerant of cooling high pressure-temperature is served as
Condenser role increases condenser area, improves condensation effect, improves unit efficiency.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is conventional refrigerant system principle sketch of the present invention；
Fig. 2 is that the present invention carries out system principle schematic diagram when heating compensation work；
Fig. 3 is the schematic diagram of heater and indoor heat exchanger pipeline location in the present invention.
Specific embodiment
As shown in Figures 1 to 3, the invention proposes a kind of air conditioners, comprising: compressor 1, outdoor heat exchanger 4 and interior are changed
Hot device 6 and throttle mechanism 5, and compressor 1, outdoor heat exchanger 4, throttle mechanism 5 are circuited sequentially with indoor heat exchanger 6 and are connected to,
In process of refrigerastion, outdoor heat exchanger 4 is condenser, and indoor heat exchanger 6 is evaporator, the high temperature and pressure that compressor 1 exports
Refrigerant is flowing to indoor heat exchanger 6, compressor 1 and outdoor heat exchange by the heat exchange of outdoor heat exchanger 4 cooling and throttle mechanism decompression
A branch 3 is also connected between device 4, one end of branch 3 is connected on the exhaust pipe of compressor 1, and branch 3, which is equipped with, is located at room
Interior heater 7 opens branch 3 when needing heating compensation, and the high temperature and pressure refrigerant for flowing out compressor flows through heater 7 etc.
It is same as condenser, and heater 7 is located at interior, the exhaust of high pressure-temperature is condensed in the inside, heated to environment, is realized
Freeze heating compensation, promotes room temperature, flow to outdoor heat exchanger again by the refrigerant of heater, directly take away indoor heat exchanger
Excessive refrigerating capacity reduces refrigerating capacity, while using the cooling capacity of the part, the refrigerant of cooling high pressure-temperature serves as condenser angle
Color increases condenser area, improves condensation effect, improves unit efficiency.
In the present invention, the pipeline between outdoor heat exchanger 4 and compressor 1 is equipped with reversal valve 2, the conduit entrance of branch 3
It being connected on reversal valve 2, the refrigerant that reheating flows out compressor when compensation is opened only passes through heater and flow to outdoor heat exchanger,
Guarantee that effect maximizes, while check valve is set on the pipe outlet of branch 3, avoids the pressure high temperature hot gas in conventional refrigerant
Into heater, heater is isolated in except system.
In the present invention, reversal valve 3 is the electric change valve controlled by controller, passes through air-conditioning system integrative control.
In the present invention, the setting of heater 7 in heat exchanger 6, is wholely set indoors with indoor heat exchanger 6, and is located at air inlet
Side, the heat exchanger tube of heater 7 and the heat exchanger tube of indoor heat exchanger 6 are arranged side by side, and are incorporated into heater 7 with indoor heat exchanger 6
Together, keep structure more succinct, and be equipped with heat transmission fin between the heat exchanger tube of heater 7 and the heat exchanger tube of indoor heat exchanger 6,
When not needing refrigeration heating compensation, passes through in heater 7 without refrigerant, by the thermally conductive of fin, improve changing for indoor heat exchanger 6
Heat area further increases the efficiency of unit；Wherein the heat transmission fin can be Integral finned heat exchanger.
