Description

Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner.
Background
When the outdoor environment temperature is low and the humidity is high, a frost layer is easy to form on a heat exchanger positioned outdoors in the air conditioner in the heating process.

Referring to fig. 1, an air conditioner 100 according to an embodiment of the present invention includes a chassis 10, a first heat exchanger 20, a first throttle valve 30, and a fluid pipe 40, wherein the first heat exchanger 20 and the first throttle valve 30 are disposed on the fluid pipe 40, the first heat exchanger 20 is disposed above the chassis 10, the fluid pipe 40 includes a deicing pipe section 41, the deicing pipe section 41 is in contact with the chassis 10, and the deicing pipe section 41 is used to enable a refrigerant to flow to the first throttle valve 30 when the air conditioner 100 is in a heating mode, so that the refrigerant flows from the first throttle valve 30 to the first heat exchanger 20.
In the air conditioner 100 according to the embodiment of the invention, since the refrigerant flows from the deicing pipe section 41 to the first throttle valve 30, the refrigerant at the deicing pipe section 41 is a liquid with a higher temperature, and the deicing pipe section 41 contacts the chassis 10, so that the temperature of the surface of the chassis 10 is higher, and the surface of the chassis 10 is not easy to freeze, thereby improving the operation stability of the air conditioner 100. In addition, the probability of icing on the surface of the chassis 10 is reduced by the way that the deicing pipe section 41 is in contact with the chassis 10, and no additional heating device is needed, so that no additional electric energy consumption is generated in the way.
Specifically, the air conditioner 100 is an apparatus for adjusting indoor temperature and humidity. The air conditioner 100 may include an indoor unit and an outdoor unit. The base pan 10 and the first heat exchanger 20 may be components on the outdoor unit. The chassis 10 may provide support for the first heat exchanger 20, and the chassis 10 may be provided with drain holes for draining water generated when the first heat exchanger 20 is operated.
The first heat exchanger 20 may be an outdoor heat exchanger on which a frost layer is easily formed when the outdoor ambient temperature is low and the humidity is high. The air conditioner 100 may melt the frost layer on the outdoor heat exchanger into water by adjusting its own mode, specifically, switch from the heating mode to the cooling mode, and place the outdoor heat exchanger in a heat dissipation state, thereby defrosting the outdoor heat exchanger with hot air.
The first throttle valve 30 may control the pressure and flow rate of the refrigerant by adjusting the opening degree of the valve. When the air conditioner 100 is in the heating mode, the refrigerant may be changed from a liquid having a higher temperature to a gas having a lower temperature through the first throttle valve 30. The first throttle valve 30 may be in communication with the first heat exchanger 20 via a fluid conduit 40. The fluid conduit 40 is a conduit for transporting a refrigerant, and the fluid conduit 40 includes a plurality of pipe sections, wherein the deicing pipe section 41 is in contact with the chassis 10.
After defrosting, the water generated on the first heat exchanger 20 may drip onto the bottom chassis 10, and the water may be discharged through the drain holes on the bottom chassis 10. In the heating mode, before the refrigerant passes through the first throttle valve 30, the refrigerant flowing to the first heat exchanger 20 in the deicing pipe section 41 is a liquid with a higher temperature, which makes the temperature of the deicing pipe section 41 higher. Since the de-icing tube section 41 is in contact with the chassis 10, heat can be transferred from the de-icing tube section 41 to the chassis 10, thereby raising the chassis 10 and reducing the probability of icing of the chassis 10.
Referring to fig. 1, in some embodiments, the air conditioner 100 further includes a compressor 50, a first reversing valve 60 and a second heat exchanger 70, wherein the compressor 50, the first reversing valve 60 and the second heat exchanger 70 are all disposed on the fluid pipeline 40, and the first reversing valve 60 is used for flowing the refrigerant to the first heat exchanger 20 so that the refrigerant flows from the first heat exchanger 20 to the second heat exchanger 70 when the air conditioner 100 is in the cooling mode;
the first reversing valve 60 is used to flow the refrigerant to the second heat exchanger 70 when the air conditioner 100 is in the heating mode, so that the refrigerant flows from the second heat exchanger 70 to the first heat exchanger 20.
In this way, the first reversing valve 60 can control the flow direction of the refrigerant, and when the air conditioner 100 is in different modes, the first reversing valve 60 can control the flow direction of the refrigerant to different heat exchangers, thereby realizing the functions of cooling and heating of the air conditioner 100.
Specifically, the main power components in the air conditioner 100 of the compressor 50 are used to compress the refrigerant and increase its pressure and temperature. The compressor 50 pressurizes the refrigerant to a high temperature and high pressure state and delivers the refrigerant to the first reversing valve 60 through the fluid line 40.
The first reversing valve 60 is used for controlling the flow direction of the refrigerant, and guiding the refrigerant to different heat exchangers according to requirements. The first reversing valve 60 may be a four-way valve, a five-way valve, or the like. When the air conditioner 100 is in the cooling mode, the first reversing valve 60 is used for making the refrigerant flow to the first heat exchanger 20, and when the refrigerant in the high-temperature and high-pressure state passes through the first heat exchanger 20, the refrigerant exchanges heat with the outdoor air, transfers heat to the outdoor air, cools itself, and liquefies into a liquid refrigerant with higher temperature.
The liquid refrigerant with higher temperature can be changed into the liquid refrigerant with lower temperature after throttling treatment. The liquid refrigerant having a low temperature may enter the second heat exchanger 70, and in the second heat exchanger 70, the liquid refrigerant having a low temperature absorbs heat of indoor air, evaporates itself into a gaseous refrigerant, and then returns to the compressor 50 through the fluid pipe 40 and again through the first reversing valve 60.
The first reversing valve 60 is used to flow the refrigerant to the second heat exchanger 70 when the air conditioner 100 is in the heating mode. When the high-temperature and high-pressure refrigerant gas passes through the second heat exchanger 70, the condensing and liquefying heat is released, and the high-temperature and high-pressure refrigerant gas can be changed into a liquid refrigerant with higher temperature. The liquid refrigerant with higher temperature flows through the deicing pipe section 41 to raise the temperature of the deicing pipe section 41, thereby raising the temperature of the chassis 10 and further reducing the probability of icing of the chassis 10. The liquid refrigerant with higher temperature is further conveyed to the first throttle valve 30, and the liquid refrigerant with higher temperature is changed into the liquid refrigerant with lower temperature under the action of the first throttle valve 30.
The liquid refrigerant with lower temperature enters the first heat exchanger 20, and in the first heat exchanger 20, the liquid refrigerant with lower temperature can absorb heat of indoor air, is vaporized into a gaseous refrigerant, and then returns to the compressor 50 through the fluid pipeline 40 and the first reversing valve 60 again.
Referring to fig. 1, in some embodiments, the air conditioner 100 further includes a refrigerant cooler 80 and a driving plate 90, wherein the refrigerant cooler 80 is in contact with the driving plate 90, the refrigerant cooler 80 is used for cooling the driving plate 90, and the driving plate 90 is electrically connected with the compressor 50 for driving the compressor 50 to operate.
In this way, the refrigerant cooler 80 can timely take away the heat of the driving plate 90, so as to avoid the failure of the driving plate 90 caused by overheating, thereby improving the operation stability of the driving plate 90 and further improving the working stability of the compressor 50.
Specifically, the refrigerant cooler 80 is a device for cooling the driving plate 90, and removes heat of the driving plate 90 by contact with the driving plate 90, thereby avoiding overheating. The refrigerant cooler 80 may be in communication with the fluid conduit 40, and the refrigerant may flow in the refrigerant cooler 80. The drive plate 90 and the compressor 50 may be connected by wires, the drive plate 90 may be capable of transmitting control signals, the wires may be capable of transmitting control signals, and the compressor 50 may be capable of receiving control signals.
Further, the refrigerant heat dissipation device may include a refrigerant heat dissipation tube and a radiator disposed on the refrigerant heat dissipation tube, the refrigerant heat dissipation tube may be connected in the refrigerant pipeline, the refrigerant heat dissipation tube may contact the driving plate 90, and heat dissipated by the driving plate 90 may be transferred during the flow of the refrigerant. The radiator may be used to radiate heat of the refrigerant radiating pipe to the outside, so that the refrigerant radiating pipe can continuously exchange heat with the driving plate 90.
Referring to fig. 1, in some embodiments, the air conditioner 100 further includes a second throttle valve 101, the second throttle valve 101 is disposed on the fluid pipeline 40, when the air conditioner 100 is in the cooling mode, the first throttle valve 30 is turned on, and the second throttle valve 101 is used for throttling the refrigerant;
when the air conditioner 100 is in the heating mode, the first throttle valve 30 is used for throttling the refrigerant, and the second throttle valve 101 is turned on; the refrigerant cooler 80 is disposed between the first throttle valve 30 and the second throttle valve 101.
In this manner, when the air conditioner 100 is in different modes, the first and second throttle valves 30 and 101 can implement different functions, thereby implementing the cooling and heating cycles of the air conditioner 100. The refrigerant cooler 80 is disposed between the first throttle valve 30 and the second throttle valve 101 to reduce the probability of condensation of the driving plate 90.
Specifically, the second throttle valve 101 may control the pressure and flow rate of the refrigerant by adjusting the opening degree of the valve. When the air conditioner is in the cooling mode, the refrigerant can be changed from the liquid with higher temperature to the gas with lower temperature after passing through the second throttle valve 101. The second throttle 101 may be in communication with the second heat exchanger 70 through the fluid conduit 40.
During the operation of the driving plate 90, the driving plate 90 emits more heat, and if the temperature of the cooling medium for cooling the driving plate 90 is too low, condensation may be generated on the surface of the driving plate 90. When the air conditioner 100 is in the cooling mode, the refrigerant sequentially flows through the compressor 50, the first reversing valve 60, the first heat exchanger 20, the first throttle valve 30, the deicing pipe section 41, the refrigerant cooler 80, the second throttle valve 101, the second heat exchanger 70, the first reversing valve 60, and the compressor 50. The refrigerant with higher temperature flows through the first throttle valve 30, at this time, the first throttle valve 30 is turned on, the refrigerant with higher temperature can flow to the refrigerant cooler 80, in the area of the refrigerant cooler 80, the refrigerant with higher temperature can cool the driving plate 90 contacted with the refrigerant cooler 80, and because the refrigerant at this time does not pass through the second throttle valve 101, the refrigerant is not throttled into liquid with lower temperature, so the temperature of the refrigerant at this time is higher, and the probability of condensation of the driving plate 90 is lower.
When the air conditioner is in the heating mode, the refrigerant sequentially flows through the compressor 50, the first reversing valve 60, the second heat exchanger 70, the second throttle valve 101, the refrigerant cooler 80, the deicing pipe section 41, the first throttle valve 30, the first heat exchanger 20, the first reversing valve 60, and the compressor 50. The refrigerant with higher temperature flows through the second throttle valve 101, at this time, the second throttle valve 101 is turned on, the refrigerant with higher temperature can flow to the refrigerant cooler 80, in the area of the refrigerant cooler 80, the refrigerant with higher temperature can cool the driving plate 90 contacted with the refrigerant cooler 80, and because the refrigerant at this time does not pass through the first throttle valve 30, the refrigerant is not throttled into liquid with lower temperature, so the temperature of the refrigerant at this time is higher, and the probability of condensation of the driving plate 90 is lower.
Meanwhile, the refrigerant flows through the deicing pipe section 41 before flowing into the first throttle valve 30, so that the refrigerant in the deicing pipe section 41 is liquid with higher temperature, the temperature of the deicing pipe section 41 is higher, the chassis 10 is raised, and the probability of icing of the chassis 10 is reduced.
Referring to fig. 2, in some embodiments, the air conditioner 100 further includes a second reversing valve 102, the second reversing valve 102 includes a first valve block 103 and a second valve block 104 connected to the first valve block 103, and the refrigerant cooler 80 is disposed between the first valve block 103 and the first throttle valve 30;
