Detailed Description
Referring to fig. 1 to 9, according to an embodiment of the present invention, there is provided a flash device including a first housing 01, the first housing 01 forming a first refrigerant accommodating chamber 011, a second housing 02 being disposed around an outer peripheral wall of the first housing 01, a second refrigerant accommodating chamber 021 being formed between the second housing 02 and the first housing 01, a refrigerant in the first refrigerant accommodating chamber 011 being different from a refrigerant in the second refrigerant accommodating chamber 021 in temperature, it being understood that the first housing 01 has a gas supplementing outlet 013, a first refrigerant inlet 014, a first refrigerant outlet 015, and the second housing 02 has a second refrigerant inlet 022, a second refrigerant outlet 023. In this technical scheme, the second casing 02 is sleeved on the outer peripheral wall of the first casing 01, when the first refrigerant accommodating cavity 011 and the second refrigerant accommodating cavity 021 both have refrigerants, the heat exchange effect will be performed due to the temperature difference between the two refrigerants, specifically, under the heat exchange effect of the high-temperature refrigerant, the liquid-phase refrigerant in the low-temperature refrigerant changes phase into gas phase, and when the flash device is assembled in a corresponding air conditioning system, the gas-phase refrigerant will enter the second-stage air suction port of the compressor 03 provided in the air conditioning system through the air supply outlet 013 to realize the air supply function. In this technical solution, since the second casing 02 is sleeved on the outer peripheral wall of the first casing 01, the contact area between the refrigerant in the second refrigerant accommodating cavity 021 and the first casing 01 is greatly increased, so that the gas phase ratio of the refrigerant in the flash evaporator and the refrigerant in the first refrigerant accommodating cavity 011 can be strongly increased, and the liquid carrying amount in the air supplementing refrigerant passing through the flash evaporator is greatly reduced.
The specific positions of the air-supplementing outlet 013, the first refrigerant inlet 014 and the first refrigerant outlet 015 may be flexibly set, for example, the first refrigerant inlet 014 and the first refrigerant outlet 015 may be simultaneously set on the top end, the bottom end or the side wall of the first housing 01 of the flash device, and the air-supplementing outlet 013 should be set on the top end of the first housing 01 based on the requirement of the air-supplementing function. For the second refrigerant inlet 022 and the second refrigerant outlet 023, preferably, the second refrigerant inlet 022 is located at two opposite sides of the second shell 02, so as to ensure that the refrigerant therein can have the maximum flow, thereby ensuring the heat exchange efficiency.
In order to further improve the heat exchange efficiency of the flash evaporator, preferably, a reinforced heat exchange structure 012 is further configured on the outer peripheral wall of the first housing 01 corresponding to the second refrigerant accommodating chamber 021, and the reinforced heat exchange structure 012 may include, for example, a plurality of continuous teeth extending toward the second refrigerant accommodating chamber 021, and further, the cross section of the teeth may be triangular or rectangular.
Considering that the flash evaporator is mainly used for increasing enthalpy of the refrigerant in the air conditioning system, according to the conventional design concept, at least a part of liquid-phase refrigerant needs to be reserved in the flash evaporator, therefore, preferably, the second refrigerant accommodating cavity 021 has a first projection on the outer peripheral wall of the first casing 01, an interface between the gas-phase refrigerant and the liquid-phase refrigerant in the first refrigerant accommodating cavity 011 has a second projection on the outer peripheral wall of the first casing 01, the second projection is in the first projection, and further, a part of the liquid-phase refrigerant in the first refrigerant accommodating cavity 011 is located below the first refrigerant accommodating cavity 011 corresponding to the first projection, that is, a part of the liquid-phase refrigerant in the first refrigerant accommodating cavity 011 is located outside a range (as in the liquid-phase refrigerant 0102 in fig. 6 or 8) corresponding to the first casing 01, and direct heat exchange is not performed.
The invention also provides an air conditioning system comprising the flash device 08. Specifically, as a specific embodiment of the air conditioning system, it is preferable that the air conditioning system further includes a compressor 03, a condenser 04, an evaporator 05, and a first throttling element 06, wherein the compressor 03, the condenser 04, the first throttling element 06, a flash evaporator 08, and the evaporator 05 form a refrigerant circulation circuit, the first casing 01 has a gas supplementing outlet 013, a first refrigerant inlet 014, and a first refrigerant outlet 015, the gas supplementing outlet 013 is connected to a second-stage intake port line provided in the compressor 03 through a gas supplementing line 0100, the first refrigerant inlet 014 is connected to a refrigerant outlet line provided in the first throttling element 06, the first refrigerant outlet 015 is connected to a refrigerant inlet line provided in the evaporator 05, the second casing 02 has a second refrigerant inlet 022, a second refrigerant outlet 023, and the second refrigerant inlet 022 is connected to a first-stage exhaust port line of the compressor 03, and the second refrigerant outlet 023 is connected to the gas supplementing line 0100. By adopting the technical scheme, the refrigerant in the second refrigerant accommodating chamber 021 is the first-stage exhaust refrigerant of the compressor 03, as shown in fig. 7, the first-stage exhaust refrigerant is in a full gas phase, and the temperature of the first-stage exhaust refrigerant is higher than the temperature of the refrigerant in the first refrigerant accommodating chamber 011 after the first-stage compression, so that the liquid-phase refrigerant in the first refrigerant accommodating chamber 011 at this time is subjected to heat absorption phase change into a gas-phase refrigerant, the temperature of the gas-phase refrigerant in the second refrigerant accommodating chamber 021 is correspondingly reduced, the gas-phase refrigerant after the temperature reduction and the gas-phase refrigerant in the first refrigerant accommodating chamber 011 are used for supplementing the air to the compressor through the air supplementing pipeline 0100, and more importantly, the temperature of the gas-phase refrigerant in the second refrigerant accommodating chamber 021 is reduced, so that the temperature of the air supplementing refrigerant at this time is wholly reduced, which is definitely beneficial to improving the compression performance of the second-stage refrigerant 03, namely improving the compression performance of the compressor 03, and further improving the energy efficiency of the air conditioning system.
Of course, the air conditioning system preferably further includes a second throttling element 07, wherein a refrigerant inlet of the second throttling element 07 is connected through with the first refrigerant outlet 015, and a refrigerant outlet of the second throttling element 07 is connected through with a refrigerant inlet pipe of the evaporator 05, so as to throttle the refrigerant in the air conditioning system for a second time, thereby improving the air conditioning effect.
In order to prevent the pressure of the gas-phase refrigerant flowing into the gas-compensating pipe 0100 through the second refrigerant outlet 023 from being higher than the pressure of the gas-phase refrigerant flowing into the gas-compensating pipe 0100 through the first refrigerant outlet 015, a gas-compensating backflow phenomenon is generated, preferably, a direction control element 0101 is further disposed in the gas-compensating pipe 0100 to ensure that the refrigerant in the gas-compensating pipe 0100 can only flow from the gas-compensating outlet 013 to the secondary air suction port, and it is understood that the direction control element 0101 is disposed on the pipeline between the inflow point of the gas-phase refrigerant flowing into the gas-compensating pipe 0100 through the second refrigerant outlet 023 and the first refrigerant outlet 015. Preferably, the direction control element 0101 may be a check valve, which can reduce the design difficulty and manufacturing cost of the air conditioning system.
As another specific embodiment of the air conditioning system, the air conditioning system preferably further includes a compressor 03, a condenser 04, an evaporator 05, a first throttling element 06, and a second throttling element 07, wherein the compressor 03, the condenser 04, the first throttling element 06, the flash evaporator 08, and the evaporator 05 form a refrigerant circulation circuit, the first casing 01 has a gas supplementing outlet 013, a first refrigerant inlet 014, and a first refrigerant outlet 015, the gas supplementing outlet 013 is in through-connection with a second-stage intake port line provided in the compressor 03 through a gas supplementing line 0100, the first refrigerant inlet 014 is in through-connection with a refrigerant outlet line of the first throttling element 06, the first refrigerant outlet 015 is in through-connection with a refrigerant inlet line of the evaporator 05, the second casing 02 has a second refrigerant inlet 022, a second refrigerant outlet 023, the second refrigerant inlet 022 is in through-connection with a refrigerant outlet line provided in the condenser 04, and the second refrigerant outlet 023 is in through-connection with a refrigerant inlet line of the first throttling element 06. The difference between this solution and the previous solution is that the refrigerant in the condenser 04 will first flow into the second refrigerant accommodating chamber 021, and then enter the first refrigerant accommodating chamber 011 after passing through the throttling function of the first throttling element 06.
Preferably, the compressor 03 is a two-stage enthalpy-increasing compressor. The first and second throttle elements 06, 07 may be, for example, conventional electronic expansion valves or capillary tubes.
It will be readily appreciated by those skilled in the art that the above advantageous ways can be freely combined and superimposed without conflict.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention. The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
