Detailed Description
Embodiments of the present application will be described in detail below, by way of example with reference to the accompanying drawings.
The window air conditioner 100 of the present application performs a refrigerating cycle of the window air conditioner 100 by using the compressor 10, the condenser 20, the expansion valve, and the evaporator 30. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.
The compressor 10 compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser 20. The condenser 20 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser 20 into a low-temperature and low-pressure liquid-phase refrigerant. The evaporator 30 evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor 10. The evaporator 30 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The window air conditioner 100 may adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the window air conditioner 100 refers to a portion of the refrigeration cycle including the compressor 10 and the outdoor heat exchanger, the indoor unit of the window air conditioner 100 includes the indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger are used as the condenser 20 or the evaporator 30. The window air conditioner 100 functions as a heater of a heating mode when the indoor heat exchanger is used as the condenser 20, and the window air conditioner 100 functions as a cooler of a cooling mode when the indoor heat exchanger is used as the evaporator 30.
In the related art, the variable frequency air conditioner generates heat in the operation process of variable frequency electronic control components, the larger the operation current is, the larger the heating value of the components is, the higher the temperature of the components is, the service life of the components can be reduced due to the fact that the temperature of the components is too high, potential safety hazards exist extremely, and therefore the components which are easy to generate heat are required to be radiated.
Therefore, in the window air conditioner 100 of the embodiment of the application, in order to realize heat dissipation of components which are easy to generate heat and to improve the service life of the components, after determining the operation mode of the window air conditioner 100, the water pump 50 is controlled by the outdoor environment temperature and the condensed water in the water receiving disc 40, so as to realize heat dissipation of the condensed water in the water receiving disc 40 to the components which are easy to generate heat, thereby improving the service life of the components.
A window air conditioner 100 according to an embodiment of the first aspect of the present application is described below with reference to fig. 1 to 6.
The window type air conditioner 100 according to the embodiment of the first aspect of the present application includes a housing, a refrigerator circuit, a water pan 40, a water level detector, a controller 60, a water pump 50, and an outdoor temperature sensor 80.
Specifically, an indoor air heat exchange passage and an outdoor air heat exchange passage are formed in the casing, and a refrigerant circuit is provided for circulating a refrigerant through the compressor 10, the condenser 20, the throttle device, and the evaporator 30 in this order, one of the condenser 20 and the evaporator 30 being an outdoor heat exchanger, and the other being an indoor heat exchanger. The water receiving tray 40 is provided at the bottom of the evaporator 30 for storing condensed water flowing down from the evaporator 30, and the water level detector for detecting the water level in the water receiving tray 40. The outdoor temperature sensor 80 is for detecting an outdoor ambient temperature. The controller 60 is arranged in the outdoor air heat exchange channel, the controller 60 comprises a circuit board 602 and a radiator 70, the radiator 70 is arranged on one side of the controller 60 adjacent to the water receiving disc 40, the radiator 70 is used for radiating heat of electrical components on the circuit board, the water pump 50 is arranged in the outdoor air heat exchange channel, and the water pump 50 is used for pumping condensate to the radiator 70.
For example, in the example of fig. 1 to 3, the compressor 10, the condenser 20, the throttling device, the evaporator 30, the water pan 40, the controller 60, the radiator 70, and the outdoor temperature sensor 80 are all provided in a case, the evaporator 30 is provided in an indoor air heat exchanging channel through which indoor air can flow to the evaporator and exchange heat, and the condenser 20 is provided in an outdoor air heat exchanging channel to release heat to the outside. The evaporator 30 absorbs heat from the low-temperature low-pressure refrigerant liquid flowing out of the throttle device to form low-temperature low-pressure refrigerant gas, and dehumidifies and cools the indoor air passing through the evaporator 30. The condenser 20 is used for cooling and depressurizing the high-temperature and high-pressure refrigerant gas discharged from the compressor 10 into medium-temperature and medium-pressure refrigerant liquid.
The controller 60 is used to drive the compressor 10 and control the overall operation, and the controller 60 is located outside the window type air conditioner 100, i.e., the controller 60 is located outside after the window type air conditioner 100 is installed to a corresponding position. Since the controller 60 generates heat after a long time of operation, heat dissipation of the controller 60 can be achieved by the heat sink 70.
Wherein the controller 60 is configured to:
when the window type air conditioner 100 is determined to operate in the cooling mode, the outdoor ambient temperature and the water level height in the water receiving tray 40 are obtained; when the outdoor ambient temperature reaches the preset temperature range and the condensed water is stored in the water receiving disc 40, the water pump 50 is controlled to operate so as to pump the condensed water in the water receiving disc 40 to the radiator 70, so that the heat dissipation of the radiator 70 is realized.
Specifically, as shown in fig. 4 to 6, since the cooling mode is operated when the outdoor ambient temperature is high, the outdoor ambient temperature can be detected by the outdoor temperature sensor 80, and when the outdoor ambient temperature reaches the preset temperature range, it is indicated that the outdoor ambient temperature is high at this time. Since the controller 60 is located outdoors, the temperature of the controller 60 is high and heat is generated during operation of the electrical components of the circuit board 602, thereby further increasing the temperature of the controller 60. To ensure the normal operation of the controller 60, heat dissipation is required to be performed on the controller 60, but the heat dissipation effect to the controller 60 is limited only by the heat sink 70. Therefore, when the air in the air flow channel flows through the radiator 70 to radiate, the condensate in the water pan 40 can be pumped to the radiator 70 by the water pump 50 to assist the radiator 70 to radiate, so that the air cooling radiation and the water cooling radiation are simultaneously carried out, the temperature of the controller 60 can be quickly reduced, the controller 60 can be further ensured to work normally, and the service life of the controller 60 is ensured. When the outdoor ambient temperature is outside the preset temperature range, the heat dissipation requirement of the controller 60 can be satisfied by air cooling.
According to the window type air conditioner 100 of the embodiment of the present application, by providing the radiator 70 at one side of the controller 60 adjacent to the water pan 40, the water pump 50 in the water pan 40 is turned on when the outdoor ambient temperature reaches the preset temperature range, so as to pump the condensed water onto the radiator 70. Therefore, compared with the traditional window type air conditioner, the condensed water in the water receiving disc 40 can conduct auxiliary heat dissipation on the radiator 70, and air cooling heat dissipation and water cooling heat dissipation are conducted simultaneously, so that the temperature of the controller 60 can be reduced rapidly, normal operation of the controller 60 is guaranteed, and the service life of the controller 60 is guaranteed.
According to some embodiments of the present application, as shown in fig. 5 and 6, after controlling the water pump 50 to be turned on, the controller 60 is further configured to:
at the current outdoor ambient temperature, the maximum operating frequency of the compressor 10 and the maximum operating current value of the window air conditioner 100 are increased.
Because the condensed water is pumped to the radiator 70 during the auxiliary heat dissipation, the temperature of the radiator 70 is lower, and thus the temperature of the controller 60 is lower, which means that the controller 60 can bear larger current, that is, the maximum operation current value of the window air conditioner 100 can be increased, and the higher the operation frequency of the compressor 10 is, the higher the operation current of the window air conditioner 100 is, and the higher the refrigerating capacity is at the same time. Thus, the maximum operating frequency of the compressor 10 can be increased, so that the refrigerating capacity can be increased, and the user experience can be improved.
Further, the maximum operating frequency of the compressor 10 at the current outdoor ambient temperature is the sum of the maximum operating frequency of the compressor 10 in the normal state and the frequency threshold. The maximum operation current value of the window air conditioner 100 at the current outdoor environment temperature is the sum of the maximum current value and the current threshold value of the window air conditioner 100 in the conventional state. The normal state is an operation state in which the window air conditioner 100 does not turn on the water pump 50 in the cooling mode.
To ensure stable operation of the window air conditioner 100, a maximum operating frequency and a maximum operating current value of the compressor 10 are limited at each outdoor ambient temperature interval. In the absence of auxiliary heat dissipation (i.e., pure air cooling, normal conditions), there is a defined maximum operating frequency and maximum operating current value for each outdoor ambient temperature interval. When auxiliary heat dissipation is performed, the temperature of the heat sink 70 may be reduced, and the temperature of the controller 60 may be lower, and a preset frequency variable may be added on the basis of the maximum operating frequency on the corresponding outdoor environment temperature interval, so as to obtain the maximum operating frequency of the compressor 10 at the current outdoor environment temperature. Likewise, a preset current variable may be added to the maximum operation current value over the corresponding outdoor environment temperature interval to obtain the maximum operation current value of the window air conditioner 100 at the current outdoor environment temperature.
Further, the water level detector is a water level switch 90.
After the outdoor ambient temperature reaches the preset temperature range, the controller 60 is further configured to:
judging whether the water level switch 90 in the water receiving tray 40 is closed or not;
if the judgment result is yes, the water level in the water receiving disc 40 reaches the preset water level, at this time, the condensed water in the water receiving disc 40 is enough, so that the continuous operation of the water pump 50 can be ensured, the water pump 50 is facilitated to pump the condensed water to the radiator 70, and the influence on the service life of the water pump 50 caused by idle running of the water pump 50 is avoided.
If the determination is negative, the water level in the drip tray 40 is insufficient to turn on the water pump 50. That is, the amount of condensed water in the water receiving tray 40 cannot ensure continuous operation of the water pump 50, and the water pump 50 is not required to be started to avoid idle running of the water pump 50.
According to some embodiments of the present application, as shown in fig. 5 and 6, after increasing the maximum operation frequency of the compressor 10 and the maximum operation current value of the window air conditioner 100 at the current outdoor ambient temperature;
the controller 60 is also configured to:
judging whether the water level switch 90 in the water receiving tray 40 is closed or not;
if the judgment result is yes, the water pump 50 is controlled to keep the on state;
if the determination is negative, the water pump 50 is controlled to be turned off.
Thus, when the water pump 50 is continuously operated for a while, the water level of the condensed water in the water receiving tray 40 is lowered, that is, the amount of the condensed water in the water receiving tray 40 is reduced, and it is necessary to determine the state of the water level switch 90 to determine the amount of the condensed water. The water level switch 90 is in a closed state, which indicates that enough condensed water in the water pan 40 can keep the operation of the water pump 50, and the water pump 50 is kept in an open state, so that the service life of the water pump 50 can be ensured while the auxiliary heat dissipation of the radiator 70 is realized; when the water level switch 90 is in an on state, it indicates that the amount of condensation water in the water receiving tray 40 is small and insufficient to support the operation of the water pump 50, so as to ensure that the water pump 50 can normally operate when being started once, the water pump 50 can be turned off at this time, and the water pump 50 is prevented from idling.
Further, as shown in fig. 5 and 6, after the water pump 50 is turned off, the controller 60 is further configured to:
at the current outdoor ambient temperature, the maximum operating frequency of the compressor 10 and the maximum operating current value of the window air conditioner 100 are reduced. Because of no auxiliary heat dissipation of condensed water, in order to ensure stable operation of the window air conditioner 100, the maximum operation frequency of the compressor 10 and the maximum operation current value of the window air conditioner 100 need to be adjusted back to the values in the pure air cooling state, so that excessive operation of the compressor 10 and the window air conditioner 100 is avoided.
According to some embodiments of the present application, as shown in fig. 6, the controller 60 is further configured to, before the outdoor ambient temperature reaches the preset temperature range:
judging an operation mode of the window type air conditioner 100;
if the window type air conditioner 100 is operated in the cooling mode, it is judged whether the outdoor ambient temperature reaches a preset temperature range.
Whether the controller 60 needs to perform the auxiliary heat dissipation is judged by the operation mode of the window air conditioner 100. Wherein, the dehumidification mode generally operates below the middle temperature region, i.e. the outdoor environment temperature is relatively low, so that the temperature of the controller 60 is also relatively low, and the controller 60 does not need auxiliary heat dissipation at this time; since the air supply mode does not involve the operation of the compressor 10, i.e., the heat generation of the controller 60 is less, the temperature of the controller 60 is lower, and the controller 60 does not need to assist in heat dissipation; since the heating mode is operated when the outdoor ambient temperature is low, and the controller 60 is located outdoors and the temperature is low, the controller 60 does not need to assist in heat dissipation. However, the cooling mode is operated when the outdoor environment temperature is high, and since the controller 60 is installed outdoors and the controller 60 is operated to generate heat, the temperature of the controller 60 is high, water cooling is required to assist heat dissipation, and rapid heat dissipation of the controller 60 is achieved.
According to some embodiments of the present application, as shown in fig. 1 and 2, a fan 110 is provided in the air flow channel, and the fan 110 is used to generate an air flow field to dissipate heat from the condenser 20 and the evaporator 30. The fan 110 is provided with a controller 60 on a side remote from the water pan 40, and the radiator 70 is located between the controller 60 and the fan 110. By this arrangement, the air in the air flow passage is ensured to flow to the radiator 70, and the heat dissipation of the controller 60 is realized.
In some alternative embodiments, referring to fig. 1, a control unit 601 is provided on the controller 60, and the control unit 601 is communicatively connected to the outdoor temperature sensor 80, the water level switch 90 and the water pump 50, respectively, for acquiring the outdoor ambient temperature detected by the outdoor ambient temperature sensor, the state of the water level switch 90, and controlling the water pump 50 to be turned on and off.
According to the window type air conditioner 100 of the embodiment of the application, when the window type air conditioner 100 is operated in the cooling mode, if the outdoor environment temperature is in the high temperature region (i.e. the preset temperature range), it is determined whether the water level switch 90 in the water pan 40 is closed, the water pump 50 is opened by closing the water level switch 90, the condensed water in the water pan 40 is pumped to the radiator 70, and the maximum operation frequency of the compressor 10 and the maximum operation current value of the window type air conditioner 100 are increased until the condensed water in the water pan 40 is insufficient to support the water pump 50 for operation, the water pump 50 is turned off, and the maximum operation frequency of the compressor 10 and the maximum operation current value of the window type air conditioner 100 are returned to the initial state. Thereby, heat dissipation to the controller 60 at a high temperature is realized, and the temperature of the controller 60 can be quickly reduced.
Optionally, the controller 60 is a variable frequency controller. But is not limited thereto.
A control method of the window air conditioner 100 according to the second aspect of the present application will be described with reference to fig. 4.
As shown in fig. 4, a control method of a window air conditioner 100 according to an embodiment of the second aspect of the present application includes:
when it is determined that the window air conditioner 100 is operated in the cooling mode, the outdoor ambient temperature is obtained. In the embodiment, the outdoor ambient temperature of the window air conditioner 100 is acquired by the outdoor temperature sensor 80.
When the outdoor ambient temperature reaches a preset temperature range, judging whether a water level switch 90 in the water receiving tray 40 is closed or not;
if the water level switch 90 is turned off, the water pump 50 is turned on and the maximum operation frequency of the compressor 10 and the maximum operation current value of the window air conditioner 100 are increased.
Judging the temperature range of the obtained outdoor environment temperature, when the outdoor environment temperature is in a high temperature area (namely a preset temperature range), the outdoor environment temperature is higher, the temperature of the controller 60 is higher, water cooling is needed to be adopted for assisting in heat dissipation to realize rapid heat dissipation of the controller 60, at the moment, whether the condensed water in the water receiving disc 40 can meet the water cooling requirement needs is needed to be judged, if the water level switch 90 is closed, the condensed water amount is more, the condensed water can be pumped to the radiator 70 through the water pump 50, the radiator 70 is assisted in heat dissipation of the controller 60, meanwhile, the maximum operation frequency of the compressor 10 and the maximum operation current value of the window air conditioner 100 are improved, the heat dissipation of the controller 60 is ensured, meanwhile, the refrigerating capacity of the window air conditioner 100 can be improved, and the use experience of a user is improved.
