A kind of new wind turbine of disclosed included hot and cold water circulation-supplied, specifically freezing and heating recycles original
Reason is：
Refrigeration cycle
As shown in Fig. 2, cooling down to the fresh air of feeding by the new wind turbine in summer, while cold water is provided, under the pattern
The first port of one four-way valve and the second four-way valve is connected to second port, and third port is connected to the 4th port, twin-tub compression
The high temperature and high pressure gas of machine output is divided into the first port that two-way is sent into two four-way valves, the gas collection come out from second port
After be divided into two-way, all the way be sent into condenser coil carry out cooling forms liquid refrigerants, another way is sent directly into hot coil again, condensation
The liquid refrigerants that device coil pipe comes out is divided into three tunnels, is changed after electric expansion valve carries out reducing pressure by regulating flow by plate form gas-liquid two-phase all the way
Refrigerant, the normal-temperature water to being sent into plate heat exchanger carries out heat exchange, normal-temperature water is become cold water, and gas-liquid two-phase refrigerant is by changing
Gaseous low temperature refrigerant completely is formed after heat（The temperature is higher than temperature before heat exchange）, the second tunnel that condenser coil comes out passes through the
It is sent into the first evaporator coil after one electric expansion valve reducing pressure by regulating flow, is once cooled down to the high humidity high fever fresh air of feeding, is made
It obtains air themperature to decrease, third road liquid refrigerants after the second electric expansion valve reducing pressure by regulating flow by being sent into the second evaporator plate
Pipe, the fresh air after once cooling down is cooled down twice, the temperature value after reducing temperature twice is relatively low, thus by hot coil again into
Row heat is gone up because what is be sent into hot coil again is initial high temperature and high pressure gas, it is achieved that the lower fresh air of temperature into
Row heat is gone up, and complies with human comfort's temperature value, then the refrigerant that comes out of hot coil by after reheating electric expansion valve with condensation
The refrigerant that device coil pipe comes out is collected, and the gaseous coolant and plate heat exchanger that first evaporator coil comes out come out complete
Complete gaseous low temperature refrigerant is sent into the 4th port of the first four-way valve after collecting, and is sent into the corresponding air-breathing of compressor high pressure chest
Mouthful, formation circulation loop, and the low-pressure gaseous refrigerant that the second evaporator coil comes out, it is sent into the 4th port of the second four-way valve,
And it is sent into the corresponding air entry of compressor low pressure chamber, form another circulation loop.
In entire cyclic process, plate heat exchanger is for reducing water temperature, by cold feed to radiating system or wind
Machine coil pipe gives indoor refrigeration, and two evaporator coils are used to reduce and dehumidify to new air temperature, wherein the first evaporator plate is effective
In preliminary cooling, the second evaporator coil dehumidifies for deep temperature reduction, and fresh air is by after cool-down dehumidification, then passes through reheating coil pipe liter
Temperature processing, to allow the indoor fresh air of feeding to reach the temperature and humidity of human comfort.
Heating cycle
As shown in figure 3, heating up in winter to the fresh air of feeding by the new wind turbine, while hot water is provided, under the pattern
The first port of one four-way valve and the second four-way valve is connected to the 4th port, and second port is connected to third port, twin-tub compression
Machine sends out high temperature and high pressure gas and is divided into two-way two four-way valves of feeding, wherein the high temperature and high pressure gas that the first four-way valve comes out is divided into
Two-way carries out primary heating, another way is sent into board-like change wherein being sent into the first evaporator coil all the way to the low temperature fresh air of entrance
Hot device heats the water at low temperature being passed through, and forms hot water and sends out, and the high temperature and high pressure gas that the second four-way valve comes out is sent into the
Two evaporator coils carry out reheating to the fresh air after primary heating, and the first evaporation gas coil pipe and the second evaporator coil come out
Room temperature liquid refrigerants gas-liquid two-phase refrigerant is formed after the first electric expansion valve and the second electric expansion valve reducing pressure by regulating flow, and
The gas-liquid two-phase refrigerant come out with electric expansion valve after plate heat exchanger, which collect being sent into condenser coil, carries out heat absorption steaming
Hair forms gaseous coolant, the second port for dividing two-way to be respectively fed to the first four-way valve and the second four-way valve, and is sent from third port
To the air entry of duplex cylinder compressor, a circulation loop is integrally formed.
In entire cyclic process, plate heat exchanger supplies radiating system or fan coil to interior for water to heat up
Heating, two evaporator coils, which are used to heat up to fresh air, ensures that wind pushing temperature is suitable, and wet-membrane humidifier is used to humidify to fresh air, protects
It is comfortable to demonstrate,prove blasting humidity.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof;To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, and those of ordinary skill in the art still can be to this hair
Bright specific implementation mode modifies or carries out equivalent replacement to some technical characteristics, but as long as not departing from the technology of the present invention
The spirit of scheme should all cover within the scope of the technical scheme claimed by the invention.
