Background

At present, the application of the variable frequency air conditioner is more and more common, and the variable frequency air conditioner is added with a variable frequency module in a fixed frequency air conditioner. The common air conditioner frequency conversion module radiator adopts an aluminum fin radiator and is matched with forced convection heat dissipation of an air conditioner outdoor unit fan, or a refrigerant ring is adopted to cool the frequency conversion module aluminum radiator. Adopt the unable effectual high-efficient heat dissipation problem of solving frequency conversion module of aluminium fin radiator, lead to the frequency conversion module high temperature easily and make the compressor force the frequency reduction in order to reduce calorific capacity, the air conditioner refrigeration volume is not enough. The variable frequency air conditioner adopts the aluminum fin and the refrigerant ring to cool the variable frequency module, and the heat dispersion performance is better under the dual functions.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art: when the traditional single refrigerant ring flow path is used for refrigeration circulation, if a refrigerant ring is positioned in front of a throttling element, the temperature of the refrigerant ring is higher than the ambient temperature, the heat dissipation requirement of a frequency conversion module can not be met under the condition of high ring temperature, the temperature of the frequency conversion module is overhigh, the compressor is forced to carry out frequency reduction refrigeration, the refrigerating capacity is reduced, meanwhile, the supercooling degree of the refrigerant in front of the throttling element is reduced due to heat dissipation of the frequency conversion module, and the refrigerating capacity of an evaporator behind the throttling element is influenced due to the supercooling degree reduction. Thereby causing the problems of poor refrigeration effect of the air conditioner and serious system refrigeration attenuation under the condition of high ambient temperature. When refrigeration cycle is carried out, if the single refrigerant ring flow path is positioned behind the throttling element, the heat dissipation temperature of the frequency conversion module is easily lower than the dew point temperature to generate condensation, and the risk of short circuit and burnout of the circuit board exists.

Referring to fig. 1 to 7, an embodiment of the present disclosure provides an air conditioner.

The air conditioner provided by the embodiment of the disclosure comprises a refrigerant circulation pipeline and a radiator 3. The refrigerant circulating pipeline comprises a compressor 1, an outdoor heat exchanger 2, a throttling element 4 and an indoor heat exchanger 5 which are sequentially connected in series. The radiator 3 comprises a first radiating pipe 6 and a second radiating pipe 7 which are in heat conducting contact with each other. The first radiating pipe 6 is connected in parallel to a first communication pipe 14 between the outdoor heat exchanger 2 and the throttling element 4, and the second radiating pipe 7 is connected in parallel to a second communication pipe 15 between the indoor heat exchanger 5 and the compressor 1. When the air conditioner operates in a refrigeration working condition, a refrigerant sequentially flows through the compressor 1, the outdoor heat exchanger 2, the first radiating pipe 6, the throttling element 4, the indoor heat exchanger 5 and the second radiating pipe 7. When the air conditioner operates in a heating working condition, the refrigerant sequentially flows through the compressor 1, the second communication pipeline 15, the indoor heat exchanger 5, the throttling element 4, the first communication pipeline 14 and the outdoor heat exchanger 2, and does not flow through the first radiating pipe 6 and the second radiating pipe 7.

Optionally, the air conditioner further comprises a plurality of valve bodies. When the plurality of valve bodies enable the air conditioner to operate in a refrigerating working condition, a refrigerant sequentially flows through the compressor 1, the outdoor heat exchanger 2, the first radiating pipe 6, the throttling element 4, the indoor heat exchanger 5 and the second radiating pipe 7. Compared with the traditional refrigerant circulation flow path, under the refrigeration working condition of the air conditioner, if the radiating pipe is positioned in front of the throttling element 4 and behind the outdoor heat exchanger 2, the temperature of the refrigerant is higher, and under the environment condition outside a high-environment greenhouse, such as the environment temperature is greater than 43 ℃, the radiating requirement of the frequency conversion module cannot be met, so that the temperature of the frequency conversion module is too high, the frequency conversion module is forced to carry out frequency reduction refrigeration, the refrigeration effect of the compressor 1 system is reduced, meanwhile, the supercooling degree of the refrigerant in front of the throttling element 4 is reduced due to the radiation of the frequency conversion module, and the supercooling degree is reduced, so that the refrigerating capacity of an evaporator behind the throttling element 4 is influenced; if the cooling tube is located behind throttling element 4, then the radiating temperature of frequency conversion module is easily less than dew point temperature and produces the condensation problem, has the risk of circuit board short circuit burnout.

This scheme adopts two refrigerant ring flow paths, and the refrigerant is the well high temperature refrigerant that flows out from outdoor heat exchanger 2 in first cooling tube 6, and the refrigerant is the low temperature refrigerant that flows out from indoor heat exchanger 5 in second cooling tube 7, and wherein, well high temperature refrigerant temperature is about 40 ℃, and the low temperature refrigerant temperature is about 20 ℃. The temperature is adjusted through the heat integration of the first radiating pipe 6 and the second radiating pipe 7, the temperature after integration can be effectively dissipated for the frequency conversion module, and meanwhile, the condensation problem is prevented. Moreover, the heat exchanger between the pipelines of the first radiating pipe 6 and the second radiating pipe 7 can be realized when the radiator 3 cools down through heat dissipation, and the supercooling degree of the refrigerant before the throttling element 4 can be increased by the low-temperature refrigerant behind the throttling element 4, so that the refrigeration effect of the air conditioner is improved, and the effect of a heat regenerator is realized.

Optionally, the air conditioner further comprises a plurality of valve bodies. When the plurality of valve bodies enable the air conditioner to operate under a refrigeration working condition, a refrigerant sequentially flows through the compressor 1, the outdoor heat exchanger 2, the first radiating pipe 6, the throttling element 4, the indoor heat exchanger 5 and the second communicating pipeline 15. When the frequency conversion module temperature is too low, in order to prevent condensation, the low-temperature refrigerant flowing out of the indoor heat exchanger 5 does not flow through the second radiating pipe 7 by controlling the plurality of valve bodies. The second radiating pipe 7 is short-circuited and the refrigerant directly flows into the compressor 1 from the indoor heat exchanger 5 through the second communication pipe 15.

Optionally, the air conditioner further comprises a plurality of valve bodies. When the air conditioner runs to a heating working condition through the valve bodies, the refrigerant sequentially flows through the compressor 1, the second communication pipeline 15, the indoor heat exchanger 5, the throttling element 4, the first communication pipeline 14 and the outdoor heat exchanger 2. When the air conditioner operates to heat the operating mode, can produce the condensation phenomenon in order to prevent that the refrigerant of low temperature low pressure from flowing through refrigerant circulation pipeline, and the outdoor temperature is low when considering the air conditioner heats the operating mode, makes refrigerant circulation pipeline not flow through first cooling tube 6 and second cooling tube 7, but only relies on the heat dissipation device, like fin assembly, forced air cooling dispels the heat to frequency conversion module.

When the refrigeration operating mode, first check valve and the one-way shutoff of second check valve, third check valve and fourth check valve one-way conduction, under four check valve effects, the refrigerant flows through first cooling tube 6 and second cooling tube 7, the refrigerant of first cooling tube 6 of flowing through is the well high temperature refrigerant after compressor 1 discharges back through the condensation of outdoor heat exchanger 2, the refrigerant of second cooling tube 7 of flowing through is exhaust low temperature refrigerant after indoor heat exchanger 5 evaporates the heat absorption, refrigerant in first cooling tube 6 and the refrigerant in the second cooling tube 7 carry out the heat exchange, radiator 3 and frequency conversion module contact heat transfer, thereby the frequency conversion module heat is taken away the realization to the heat dissipation of frequency conversion module by the refrigerant of first cooling tube 6 of flowing through and second cooling tube 7.

When the air conditioner operates to heat the operating mode, can produce the condensation phenomenon in order to prevent that the refrigerant of low temperature low pressure from flowing through refrigerant circulation pipeline, and the outdoor temperature is low when considering the air conditioner heats the operating mode, makes refrigerant circulation pipeline not flow through first cooling tube 6 and second cooling tube 7, but only relies on independent heat dissipation module forced air cooling to dispel the heat to frequency conversion module.

Alternatively, the first valve element 9 is provided as a first solenoid valve, the second valve element 10 is provided as a second non-return valve, the third valve element 11 is provided as a third non-return valve, and the fourth valve element 12 is provided as a fourth solenoid valve.

And when the refrigeration working condition is met, the first electromagnetic valve and the second one-way valve are closed, and the third one-way valve and the fourth electromagnetic valve are communicated. The refrigerant flows through first cooling tube 6 and second cooling tube 7, the refrigerant of first cooling tube 6 of flowing through is the well high temperature refrigerant after 2 condensation of outdoor heat exchanger behind the discharge of compressor 1, the refrigerant of second cooling tube 7 of flowing through is the exhaust low temperature refrigerant after 5 evaporation endotherms of indoor heat exchanger, the refrigerant flows through first cooling tube 6 and second cooling tube 7, radiator 3 and frequency conversion module contact heat transfer, thereby the frequency conversion module heat is taken away the realization to the heat dissipation of frequency conversion module by the refrigerant of first cooling tube 6 of flowing through and second cooling tube 7. Meanwhile, when the temperature of the frequency conversion module is too low, the fourth electromagnetic valve can be closed and the first electromagnetic valve is opened for preventing condensation.

When the heating working condition is operated, the first electromagnetic valve and the second one-way valve are switched on, the third one-way valve and the fourth electromagnetic valve are switched off, and the first radiating pipe 6 and the second radiating pipe 7 are short-circuited and have no refrigerant flowing through. When the air conditioner operates to heat the operating mode, can produce the condensation phenomenon in order to prevent that the refrigerant of low temperature low pressure from flowing through refrigerant circulation pipeline, and the outdoor temperature is low when considering the air conditioner heats the operating mode, makes refrigerant circulation pipeline not flow through first cooling tube 6 and second cooling tube 7, but only relies on independent heat dissipation module forced air cooling to dispel the heat to frequency conversion module.

Alternatively, the first valve element 9 is provided as a first solenoid valve, the second valve element 10 is provided as a second non-return valve, the third valve element 11 is provided as a third non-return valve, and the fourth valve element 12 is provided as a fourth capillary tube. Wherein the conducting direction of the second check valve is defined to flow from the throttling element 4 to the outdoor heat exchanger 2 through the first communication pipe 14, and the conducting direction of the third check valve is defined to flow from the outdoor heat exchanger 2 to the throttling element 4 through the first radiating pipe 6.

And when the refrigeration working condition is met, the first electromagnetic valve and the second one-way valve are closed, and the third one-way valve and the fourth capillary tube are communicated.

Meanwhile, when the temperature of the frequency conversion module is too low, the first electromagnetic valve can be opened for preventing condensation, and the pressure action of the fourth capillary tube enables the second radiating pipe 7 to be in a short-circuit state and not to have a refrigerant to pass through, and the refrigerant enters the compressor 1 through the first electromagnetic valve.

When the heating working condition is operated, the first electromagnetic valve and the second one-way valve are switched on, the third one-way valve is switched off, the second radiating pipe 7 is in a short-circuit state under the pressure action of the capillary tube, no refrigerant passes through, and the refrigerant directly flows to the compressor 1 from the indoor heat exchanger 5.
