[0032] The refrigerant quantity required for high efficient operation of the refrigeration cycle of the heat pump type refrigeration system is not a fixed value due to the different environmental temperature and function mode, and there is an optimal cycle quantity for different working conditions, and the adjustment of refrigerant cycle quantity mainly depends on the traditional double pipe or single pipe liquid accumulator, and the adjustment of refrigerant quantity of the liquid accumulator to the refrigeration system is mainly passive according to the system pressure and the environmental temperature change of the liquid accumulator, which is not ideal in adjustment accuracy or the adjustment speed is not fast enough, so that the refrigeration system is not in the optimal energy efficiency operation state.
[0033] The driving force of the liquid storage function of the single pipe liquid accumulator is derived from the temperature difference between the refrigerant at the outlet of the condenser and the wall of the liquid accumulator, when the heat pump unit is normally operated, the environmental temperature of the liquid accumulator is usually much lower than the outlet temperature of the condenser, and the excess refrigerant of the heat pump is migrated to the liquid accumulator due to the driving force generated by the temperature difference, so that the refrigeration system can be stably operated.
[0034] However, when the condenser of the refrigeration system adopts plate exchange, the liquid storage performance affects the energy efficiency of the refrigeration system: the first case is that the refrigerant surplus quantity of the unit heating is much more than that of the refrigeration, the liquid storage function of the liquid accumulator is limited, which affects the normal operation of the refrigeration system, and the energy efficiency is very low due to the too high condensing pressure; the second case is that when the unit is refrigerated, the refrigerant in the liquid accumulator is difficult to release back to the refrigeration system due to the very low environmental temperature, which causes the operation of the refrigeration system to be short of refrigerant, which also makes the energy efficiency too low.
[0035] To solve the above problems, the utility model provides a refrigerant quantity self -adaptation's refrigerating system can effectively solve the problem of refrigerant circulation quantity is too much or too low, the liquid storage function of liquid accumulator is limited thereby influence refrigerating system energy efficiency is low.
[0036] Reference Figure 1 And Figure 2 The utility model discloses a refrigerant quantity self -adaptation's refrigerating system makes the following embodiment:
[0037] The refrigerating system of the utility model embodiment includes: refrigeration pipeline 100 and liquid accumulator.
[0038] Among them, as Figure 1 Indicated, refrigeration pipeline 100 includes compressor 110, condenser 120, throttling device 130 and evaporator 140 connected in closed loop.
[0039] As Figure 2 Indicated, the liquid accumulator of this embodiment is single -tube liquid accumulator, including: liquid accumulator body 200, cooling module and heating module, and the liquid accumulator body 200 is vertically arranged and sealed, and the tank body of liquid accumulator body 200 is cylindrical, so that the inner periphery of tank body is uniformly stressed, avoids partial stress too big, improves the safety and stability of liquid accumulator body 200.
[0040] The lower end of liquid accumulator body 200 is equipped with inlet and outlet 210, and the upper end is equipped with exhaust needle valve 220, in actual use, the liquid stored is located in the lower part inside liquid accumulator body 200, forms liquid seal to inlet and outlet 210, and inlet and outlet 210 are used to release and absorb liquid, and exhaust needle valve 220 is used to discharge the gas above liquid level, to adjust the air pressure inside liquid accumulator body 200, and exhaust needle valve 220 can be used to discharge non-condensable gas in the initial stage of use, expand the space of liquid storage, so that the circulating refrigerant purity in refrigeration pipeline 100 is higher.
[0041] Cooling module and heating module are sequentially arranged in liquid accumulator body 200 from top to bottom, cooling module is located above liquid level, is used to cool and lower the gas refrigerant above the liquid level inside liquid accumulator body 200, and heating module is located below liquid level, is used to heat the liquid refrigerant inside liquid accumulator body 200.
[0042] Further, since liquid accumulator body 200 is a pressure vessel, the internal pressure changes greatly when in use, the wall body of liquid accumulator body 200 of this embodiment is a pressure-bearing component, to improve the use safety and stability of liquid accumulator body 200, is favorable for prolonging the service life of liquid accumulator body 200.
[0043] The cooling module comprises the first heat exchanger 230, and the heating module comprises the second heat exchanger 240; the first heat exchanger 230 and the second heat exchanger 240 are both spiral coil structures; heat exchange is performed by passing a heat exchange medium in the spiral coil and utilizing the temperature difference between the heat exchange medium and the internal environment of the liquid accumulator body 200 to conduct heat; the spiral coil is spirally arranged along the cylindrical inner periphery of the liquid accumulator body 200, thereby increasing the contact area of the first heat exchanger 230, the second heat exchanger 240 and the contents of the liquid accumulator body 200, increasing the heat conduction of the stored gas and liquid refrigerant, greatly improving the heat exchange efficiency, and enhancing the performance of the liquid accumulator in absorbing and releasing the refrigerant; in other embodiments, other structures can be used for cooling and heating, such as a wind cooling structure for the cooling module and an electric heating wire structure for the heating module.
[0044] In the embodiment, the heat exchange medium passed in the first heat exchanger 230 and the second heat exchanger 240 is refrigerant in a refrigeration system; after the heat exchange, the refrigerant as the heat exchange medium reenters the refrigeration cycle, greatly improves the utilization rate of the refrigerant, and realizes self-adaptive adjustment of the circulation amount of the refrigerant and reduces heat loss; in other embodiments, other heat exchange media such as water can be used.
[0045] The first heat exchanger 230 is respectively provided with a first heat exchange medium inlet 231 and a first heat exchange medium outlet 232 at two ends; in the embodiment, the first heat exchange medium inlet 231 and the first heat exchange medium outlet 232 are arranged in the horizontal direction, which is beneficial to reducing the pressure in the coil and facilitating the flow of the heat exchange medium; in other embodiments, the first heat exchange medium inlet 231 and the first heat exchange medium outlet 232 can be arranged in other directions, for example, extending in the vertical direction at the upper part of the liquid accumulator body 200.
[0046] To cool and lower the temperature of the gas in the liquid accumulator body 200, the temperature of the heat exchange medium in the first heat exchanger 230 must be lower than the internal temperature of the liquid accumulator body 200; the first heat exchange medium inlet 231 is connected to the downstream side of the throttling device 130; the refrigerant on the downstream side of the throttling device 130 is in a low-temperature and low-pressure state; the low-temperature and low-pressure refrigerant is passed into the first heat exchanger 230 from the first heat exchange medium inlet 231, thereby cooling and lowering the temperature of the gas refrigerant in the liquid accumulator body 200; the gas condenses on the coil wall in the liquid accumulator body 200 and is converted into liquid, thereby reducing the occupied volume and lowering the gas pressure in the bottle; the liquid refrigerant is absorbed from the inlet and outlet 210, thereby reducing the circulation amount of the refrigerant in the refrigeration pipeline 100; the first heat exchange medium outlet 232 is connected to the upstream side of the compressor 110; the temperature of the refrigerant in the first heat exchanger 230 is increased after the heat exchange, and the state of the refrigerant is consistent with that of the refrigerant in the refrigeration pipeline 100 on the upstream side of the compressor 110, thereby reentering the refrigeration cycle without affecting the state of the refrigerant in the pipeline.
[0047] Further, the first heat exchange medium inlet 231 is provided with a first switch valve 233. The first switch valve 233 is used to control the time when the low-temperature and low-pressure refrigerant enters the liquid accumulator. In this embodiment, the first switch valve 233 is an electromagnetic valve, which is used to precisely control the opening and closing of the first switch valve 233.
[0048] Similarly, the second heat exchanger 240 is provided with a second heat exchange medium inlet 241 and a second heat exchange medium outlet 242. In this embodiment, the second heat exchange medium inlet 241 and the second heat exchange medium outlet 242 are arranged in the horizontal direction, which is beneficial to reduce the pressure in the coil and facilitate the flow of the heat exchange medium. In other embodiments, the second heat exchange medium inlet 241 and the second heat exchange medium outlet 242 can be arranged in other directions, for example, extending in the vertical direction at the upper part of the liquid accumulator body 200.
[0049] In order to heat the gas in the liquid accumulator body 200, the temperature of the heat exchange medium in the second heat exchanger 240 must be higher than the temperature inside the liquid accumulator body 200. The second heat exchange medium inlet 241 is connected to the downstream side of the compressor 110. The refrigerant on the downstream side of the compressor 110 is in a high-temperature and high-pressure state. The high-temperature and high-pressure refrigerant enters the second heat exchanger 240 through the second heat exchange medium inlet 241, heats the liquid refrigerant inside the liquid accumulator body 200, accelerates the evaporation of the liquid refrigerant into gas, and increases the volume occupied by the gas. At the same time, the gas pressure in the bottle increases, and the liquid refrigerant is squeezed into the refrigeration pipeline 100, which increases the circulation amount of the refrigerant in the refrigeration pipeline 100. The second heat exchange medium outlet 242 is connected to the upstream side of the compressor 110. After heat exchange, the temperature of the refrigerant in the second heat exchanger 240 decreases, which is consistent with the state of the refrigerant in the refrigeration pipeline 100 on the upstream side of the compressor 110. Therefore, the refrigerant can re-enter the refrigeration cycle without affecting the state of the refrigerant in the pipeline.
[0050] Further, the second heat exchange medium inlet 241 is provided with a second switch valve 243. The second switch valve 243 is used to control the time when the high-temperature and high-pressure refrigerant enters the liquid accumulator. In this embodiment, the second switch valve 243 is an electromagnetic valve, which is used to precisely control the opening and closing of the second switch valve 243.
[0051] To realize the automatic adjustment of the refrigerant circulation amount of the refrigeration system, the refrigeration system further comprises a sensing assembly and a control assembly. The sensing assembly is configured to monitor the operating parameters of the refrigeration pipeline 100 in real time, such as refrigerant pressure, temperature, four-way valve 150 operating state, etc. The control assembly is configured to receive the operating parameters to control the operation of the cooling module and the heating module. The sensing assembly is connected with the control assembly. The monitored operating parameter signals are transmitted from the sensing assembly to the control assembly. The control assembly judges the working condition demand according to the operating parameters, and then controls the operation and stop of the cooling module and the heating module. Specifically, in this embodiment, the control assembly controls the opening and closing of the first switch valve 233 and the second switch valve 243.
[0052] The refrigeration pipeline 100 further comprises a four-way valve 150. The four-way valve 150 is provided with four ports, two of which are connected with the inlet and outlet of the compressor 110 respectively, and the other two are connected with the condenser 120 and the evaporator 140 respectively. The four-way valve 150 is used to control the working mode of the refrigeration pipeline 100. Through the four-way valve 150, the refrigeration pipeline 100 can be switched to the refrigeration mode or the heating mode, thereby expanding the applicable scenarios of the refrigeration system.
[0053] Further, the refrigeration pipeline 100 of the embodiment further comprises a gas-liquid separator 160. The gas-liquid separator 160 is located at the inlet end of the compressor 110, and is used to separate gas and liquid refrigerants, thereby improving the gas purity entering the compressor 110, preventing liquid from entering the compressor 110 to cause liquid hammer phenomenon, and ensuring the normal operation of the compressor 110.
[0054] The method for using the liquid accumulator for the refrigeration system of the embodiment is as follows: in the initial stage of use, the exhaust needle valve 220 is opened to discharge the originally stored non-condensable gas and improve the space utilization of the inside of the liquid accumulator body 200; the sensing assembly monitors the operating parameters of the refrigeration pipeline 100 in real time, such as the refrigerant pressure, temperature, working state of the four-way valve 150, and the like, the monitored operating parameter signals are transmitted to the control assembly by the sensing assembly, the control assembly judges the working condition requirements according to the operating parameters, and then adjusts the refrigerant circulation amount in the refrigeration pipeline 100: when the refrigerant in the refrigeration pipeline 100 is still excessive after being adjusted by the throttling device 130, the control assembly controls the first switch valve 233 to be opened and the second switch valve 243 to be closed, the low-temperature and low-pressure refrigerant flows into the first heat exchanger 230, the gas refrigerant in the inside of the liquid accumulator body 200 is subjected to the cooling effect and is condensed into liquid, the internal gas pressure is reduced, the inlet and outlet 210 absorbs the refrigerant, and the refrigerant in the refrigeration pipeline 100 is reduced; when the refrigerant in the refrigeration pipeline 100 is still insufficient after being adjusted by the throttling device 130, the control assembly controls the second switch valve 243 to be opened and the first switch valve 233 to be closed, the high-temperature and high-pressure refrigerant flows into the second heat exchanger 240, the liquid refrigerant in the inside of the liquid accumulator body 200 is subjected to the heating effect and is evaporated into gas, the internal gas pressure is increased, the liquid is squeezed into the refrigeration pipeline 100, and the refrigerant in the refrigeration pipeline 100 is increased.
[0055] Therefore, the liquid accumulator for the refrigeration system of the embodiment can realize effective control of the release and storage of the refrigerant by the liquid accumulator, the refrigerant content in the refrigeration pipeline 100 can be adjusted according to the operating requirements, thereby ensuring the efficient operation of the refrigeration system, effectively reducing the operating energy consumption of the air conditioning unit, and meeting different working condition requirements.
