Description

Technical Field

[0001] The utility model relates to the field of air cooling devices, and specifically relates to an air cooling device capable of reducing power consumption. Background Art

[0002] An airborne air cooling device is generally used in an indoor equipment room to provide low-temperature purified air for the heat load of an assembly workshop. As an indoor cooling device, the air cooling device generally includes a compressor, a condenser and its configured condenser fan, an evaporator and its configured evaporator fan, and a throttling device. The refrigerant output by the compressor first enters the condenser to dissipate heat, and then further cools down through the throttling device and enters the evaporator. After absorbing heat in the evaporator, it returns to the compressor. The heat dissipated by the refrigerant in the condenser is taken away by the condenser fan. Under the action of the evaporator fan, external air enters the room through the evaporator, and the heat of the external air is absorbed by the refrigerant in the evaporator. An electric heater is generally arranged on the air outlet side of the evaporator fan to heat the air sent into the room when needed.

[0003] While providing purified air, a large amount of heat is generated by the condenser of this air cooling device, and the heat generated by the condenser is directly taken away by the condenser fan, undoubtedly resulting in the problem of energy waste. Summary of the Utility Model

[0004] The utility model provides an air cooling device capable of reducing power consumption to solve the problem of heat waste generated by the condenser in the existing air cooling device.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] An air cooling device capable of reducing power consumption includes a refrigeration cycle loop composed of a compressor, a condenser, an evaporator, and a throttling device. It is characterized in that it further includes a diversion air duct, an evaporator air duct, and a condenser air duct with an electric control three-way valve in the middle. The evaporator and its configured evaporator fan are arranged in the evaporator air duct, the condenser and its configured condenser fan are arranged in the condenser air duct, one end of the diversion air duct is communicated with the evaporator air duct, and the other end of the diversion air duct is connected to the electric control three-way valve in the condenser air duct.

[0007] Further, a diversion fan is installed in the diversion air duct.

[0008] Further, it further includes a controller, and the controller is respectively electrically connected to the electric control three-way valve and the diversion fan for control.

[0009] Further, it further includes a temperature sensor for detecting the temperature of the air in the evaporator air duct, and the temperature sensor is electrically connected to the controller for signal transmission.

[0010] Further, it further includes a pressure sensor for detecting the condenser pressure, and the pressure sensor is electrically connected to the controller for signal transmission.

[0011] In the present utility model, an electronically controlled three-way valve is used as a bypass component for the heat dissipation of the condenser, and the electronically controlled three-way valve is controlled by the controller. When the temperature of the air sent by the evaporation fan is lower than the set value, the controller controls the electronically controlled three-way valve to switch to connect the condensation air duct and the diversion air duct, so that the heat generated by the condenser is sent into the evaporation air duct through the diversion air duct along with the hot air formed by the condensation fan. Thus, the air sent by the evaporation fan can be heated, the heat generated by the condenser can be recycled, the power consumption of the electric heater can be reduced, and further the power consumption of the entire air conditioning equipment can be reduced. The diversion fan arranged in the diversion air duct is used to provide power for the hot air formed by the condensation fan to pass through the diversion air duct when the condensation air duct and the diversion air duct are far apart.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] 1. The present utility model can recycle the heat generated by the condenser when needed, thereby reducing the overall power consumption of the air conditioner and saving energy.

[0014] 2. The present utility model has a simple structure, is easy to manufacture, and is safe and reliable;

[0015] 3. The present utility model has a simple principle, a wide application range, and can be widely applied to air-cooled devices. Description of the Drawings

[0016] Figure 1 is the structural schematic diagram of an embodiment of the present utility model. Detailed Embodiment

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0018] As Figure 1 shown, this embodiment discloses an air-cooled device capable of reducing power consumption, which includes a refrigeration cycle loop composed of a compressor 10, a condenser 2 configured with a condensation fan 1, an evaporator 5 configured with an evaporation fan 13, and a throttling device 7. In the refrigeration cycle loop, the refrigerant outlet of the compressor 10 is connected to the inlet of the condenser 2 through a pipeline, the outlet of the condenser 2 is connected to the inlet of the throttling device 7 through a pipeline, the outlet of the throttling device 7 is connected to the inlet of the evaporator 5 through a pipeline, and the outlet of the evaporator 5 is connected to the refrigerant return port of the compressor 10 through a pipeline, thereby forming a refrigerant cycle loop.

[0019] Among them, the condenser 2 and the configured condensation fan 1 are arranged inside the condenser air duct 6 with an electronically controlled three-way valve 4 in the middle. Specifically, the middle of the condenser air duct 6 is disconnected, and the first valve port and the second valve port of the electronically controlled three-way valve 4 are respectively connected to both ends of the disconnected middle of the condenser air duct 6. The condenser 2 is arranged in the condenser air duct 6 and outside the first valve port of the electronically controlled three-way valve 4, and the configured condensation fan 1 of the condenser 2 is arranged in the condenser air duct 6 and outside the second valve port of the electronically controlled three-way valve 4.

[0020] The evaporator 5 and the configured evaporation fan 13 are arranged inside the evaporator air duct 14. Among them, the evaporator 5 is arranged in the evaporator air duct 14 near the air inlet of the evaporator air duct 14, and the evaporation fan 13 is arranged in the evaporator air duct 14 near the air outlet of the evaporator air duct 14.

[0021] The condenser air duct 6 is communicated with the evaporator air duct 14 through the diversion air duct 3. Specifically, one end of the diversion air duct 3 is connected to the third valve port of the electronically controlled three-way valve 4, and the other end of the diversion air duct 3 is communicated to the position between the evaporator 5 and the evaporation fan 13 in the evaporator air duct 14.

[0022] This embodiment further includes a controller 9, and the controller 9 is electrically connected to the electronically controlled three-way valve 4 for control. When the controller 9 controls the electronically controlled three-way valve 4 to keep the condenser air duct 6 conducting, the heat generated by the condenser 2 is carried away by the wind formed by the condensation fan 1. When the controller 9 controls the electronically controlled three-way valve 4 to switch to connect the condenser air duct and the diversion air duct 3, the heat generated by the condenser 2 affects the temperature of the wind in the evaporator air duct 14 through the diversion air duct 3, so that the wind passing through the evaporator 5 formed by the evaporation fan 13 in the evaporator air duct 14 is heated. This situation is applicable to the occasion where the distance between the condenser air duct 6 and the evaporator air duct 14 is relatively close.

[0023] If the distance between the condenser air duct 6 and the evaporator air duct 14 is relatively far, a diversion fan 12 is arranged inside the diversion air duct 3, and the controller 9 is electrically connected to the diversion fan 12 for control. When the controller 9 controls the electronically controlled three-way valve 4 to switch to connect the condenser air duct and the diversion air duct 3, the heat generated by the condenser 2 is carried into the evaporator air duct 14 by the wind force of the diversion fan 12, so that the wind passing through the evaporator 5 formed by the evaporation fan 13 in the evaporator air duct 14 is heated. This situation is applicable to the occasion where the distance between the condenser air duct 6 and the evaporator air duct 14 is relatively far.

[0024] In the above process, the controller 9 judges whether to switch the electronically controlled three-way valve 4, which can be switched according to the set time. The specific switching time can be determined according to the actual situation during use. For example, according to the temperature change law of the actual evaporation fan 13 sending air to the room, the switching time is determined.

[0025] In this embodiment, a temperature sensor 8 is further provided in the evaporator air duct 14 for detecting the temperature of the air passing through the evaporator 5 formed by the evaporation fan 13. The temperature sensor 8 is electrically connected to the controller 9 for signal transmission. The controller 9 determines whether to switch the electronically controlled three-way valve 4 based on the signal collected by the temperature sensor 8, so as to introduce the heat generated by the condenser 2 into the evaporator air duct 14 and control the opening degree of the electronically controlled three-way valve 4. When the temperature in the evaporator air duct 14 is less than the set value, the controller 9 controls the electronically controlled three-way valve 4 to switch to connect the condenser air duct 6 and the diversion air duct 3; and if the temperature in the evaporator air duct 14 is much less than the set value, the controller 9 controls the electronically controlled three-way valve 4 to have a larger opening degree when connecting the condenser air duct 6 and the diversion air duct 3.

[0026] In addition, in this embodiment, a pressure sensor 11 is further arranged in the pipeline between the condenser 2 and the throttling device 7. The pressure sensor 11 is used for detecting the refrigerant pressure flowing out of the condenser 2. The pressure sensor 11 is electrically connected to the controller 9 for signal transmission. By detecting the refrigerant pressure, when the condensation pressure increases, the electronically controlled three-way valve 4 can be preferentially rotated towards the condenser air duct 6 to increase the condensation heat dissipation and maintain the condensation pressure at a normal level.
