Description

Technical Field

[0001] This invention relates to the field of cold chain logistics technology, and more specifically, to an on-board refrigeration device and a cold chain transport vehicle. Background Technology

[0002] With the advancement of technology, people have increasingly higher requirements for the preservation of goods, and the logistics industry is becoming more and more widespread. While ensuring the required delivery speed, various logistics equipment are also paying increasing attention to the control of temperature and humidity inside the vehicle during transportation. A condenser is a component of a refrigeration system, a type of heat exchanger, that converts gas or vapor into liquid, rapidly transferring heat from the pipes to the surrounding air.

[0003] However, in practical applications, there is a problem: in order to maintain the temperature in the refrigerated container within the set range, the condenser of the current cold chain logistics equipment needs to work continuously for a long time. The heat discharged during the condensation process is generally released into the atmosphere, resulting in energy waste and air pollution. Summary of the Invention

[0004] The problem solved by this invention is the technical problem of the lack of utilization of heat generated during the condensation process and the pollution of the environment. It achieves the technical effect of storing and effectively utilizing the heat discharged from the condenser.

[0006] Compared with existing technologies, the technical advantages achieved by this solution are as follows: the refrigerant circulation pipeline connects the compressor, the first condenser, and the evaporator; the compressor compresses the gas and converts it into a high-temperature gas, driving the refrigerant to circulate in the refrigerant circulation pipeline; the first condenser performs initial condensation on the high-temperature exhaust gas from the compressor; the condensed gas exchanges heat with the outside air through the evaporator, achieving a cooling effect; and a heat storage component surrounds at least a portion of the surface of the first condenser to absorb and store heat from the first condenser.

The vehicle-mounted refrigeration unit also has a bypass pipeline. One end of the bypass pipeline connects to the compressor outlet and the first valve, and the other end connects to the first condenser outlet and the evaporator. This allows the high-temperature exhaust gas discharged from the compressor outlet to flow directly to the evaporator through the bypass pipeline without passing through the first condenser. A second valve is installed on the bypass pipeline, which controls the opening and closing of the bypass pipeline and the flow rate of the high-temperature exhaust gas passing through it. Furthermore, users can adjust the flow direction and flow rate of the high-temperature exhaust gas according to their needs by adjusting the states of the first and second valves.

[0034]

Example 1

[0035] See Figures 1-2 The present invention provides an on-board refrigeration device 100, comprising: a refrigerant circulation pipeline 110; a compressor 120 for driving refrigerant to circulate in the refrigerant circulation pipeline 110; a first condenser 130, the inlet of the first condenser 130 being connected to the outlet of the compressor 120 through the refrigerant circulation pipeline 110, and the outlet of the first condenser 130 being connected to the inlet of the evaporator 140 through the refrigerant circulation pipeline 110; an evaporator 140, the outlet of the evaporator 140 being connected to the inlet of the compressor 120 through the refrigerant circulation pipeline 110; and a heat storage component 150, the heat storage component 150 surrounding and covering at least a portion of the surface of the first condenser 130, the heat storage component 150 for absorbing and storing heat from the first condenser 130.

[0036] Specifically, the compressor 120, the first condenser 130, and the evaporator 140 are connected sequentially via a refrigerant circulation pipe 110 to form a closed loop. The refrigerant circulates between the compressor 120, the first condenser 130, and the evaporator 140 through the refrigerant circulation pipe 110. The compressor 120 drives the refrigerant to circulate in the refrigerant circulation pipe 110. The outlet of the compressor 120 is connected to the inlet of the first condenser 130, the outlet of the first condenser 130 is connected to the inlet of the evaporator 140, and the outlet of the evaporator 140 is connected to the inlet of the compressor 120. At least a portion of the surface of the first condenser 130 is also surrounded by a heat storage component 150, which is used to absorb and store the heat generated when the first condenser 130 is operating.

[0037] The working principle of the vehicle-mounted refrigeration device 100 is as follows: The high-temperature exhaust gas from the compressor 120 enters the first condenser 130, achieving a condensation process. Simultaneously, after a period of time, the heat storage component 150, which surrounds at least part of the surface of the first condenser 130, absorbs and stores the heat generated during the condensation process. After condensation, the high-temperature exhaust gas cools and flows to the evaporator 140, where it exchanges heat with the outside air, achieving a cooling effect. The heat storage component 150 absorbs and stores the heat from the first condenser 130, avoiding resource waste, reducing environmental pollution, and improving energy utilization.

[0038] Preferably, an oil separator 115 may be provided between the compressor 120 and the first condenser 130. The refrigerant gas discharged from the compressor 120 enters the oil separator 115 for oil-gas separation and then enters the first condenser 130 for the first condensation. A vapor separator 117 may be provided between the evaporator 140 and the compressor 120, and the vapor separator 117 is located on the inlet side of the compressor 120 to prevent liquid refrigerant from being sucked into the air inlet of the compressor 120, which would cause liquid slugging and damage to the compressor 120.

[0039] Preferably, the high-temperature exhaust temperature in the compressor 120 reaches 70℃~100℃, and the high-temperature exhaust provides heat to the heat storage unit, thereby achieving energy saving and emission reduction and improving the efficient use of energy.

[0040] Preferably, the heat storage component 150 can be made of a new type of heat storage phase change material (GX). The new type of heat storage phase change material (GX) is a high-density energy storage material. The phase change temperature range of the heat storage phase change material (GX) is 20℃~55℃, and it has a good heat storage effect.

[0041] Furthermore, the vehicle-mounted refrigeration device 100 also includes: a first valve 111, which is located in the refrigerant circulation pipeline 110 and between the outlet of the compressor 120 and the inlet of the first condenser 130; a bypass pipeline 112, one end of which is connected between the outlet of the compressor 120 and the first valve 111, and the other end of which is connected between the outlet of the first condenser 130 and the evaporator 140; and a second valve 113, which is located in the bypass pipeline 112.

[0042] For example, the first valve 111 is located in the refrigerant circulation pipeline 110 and between the outlet of the compressor 120 and the inlet of the first condenser 130. The first valve 111 can control the opening and closing of the refrigerant circulation pipeline 110 from the outlet of the compressor 120 to the inlet of the first condenser 130, and can control the flow rate of high-temperature exhaust gas from the outlet of the compressor 120 to the inlet of the first condenser 130 by controlling the state of the first valve 111; the vehicle-mounted refrigeration device 100 is also provided with a bypass pipeline 112, bypassing... One end of the bypass pipe 112 is connected between the outlet of the compressor 120 and the first valve 111, and the other end is connected between the outlet of the first condenser 130 and the evaporator 140. This means that the high-temperature exhaust gas discharged from the compressor 120 outlet can bypass the first condenser 130 and flow directly to the evaporator 140 through the bypass pipe 112. A second valve 113 is provided on the bypass pipe 112, which controls the opening and closing of the bypass pipe 112 and the flow rate of the high-temperature exhaust gas passing through it. Users can also adjust the flow direction and flow rate of the high-temperature exhaust gas by adjusting the states of the first valve 111 and the second valve 113 according to their needs.

[0043] Preferably, the first valve 111 and the second valve 113 can be ball valves with low flow resistance, which facilitates pipeline maintenance and the adjustment of related fluids.

[0044] Furthermore, the vehicle-mounted refrigeration device 100 also includes a second condenser 114, which is connected between the outlet of the first condenser 130 and the inlet of the evaporator 140 via a refrigerant circulation pipeline 110.

[0045] Specifically, a second condenser 114 is provided between the outlet of the first condenser 130 and the inlet of the evaporator 140. The second condenser 114 is used to further condense the high-temperature exhaust gas discharged from the compressor 120 and improve the condensation efficiency.

[0046] Preferably, the second condenser 114 is a fan condenser, and a condensing fan is provided on the second condenser 114 to quickly exhaust the air around the second condenser 114 for heat dissipation.

[0047] Furthermore, the vehicle-mounted cold storage device is installed in the cold chain transport vehicle 200, which includes a compartment 210, an evaporator 140 for applying cooling to the compartment 210, and a heat storage component 150 for applying heat to the compartment 210.

[0048] For example, the vehicle-mounted cold storage device is installed in a refrigerated transport vehicle 200, which includes a cargo compartment 210. When the vehicle-mounted cold storage device is running, the evaporator 140 applies cooling energy to the cargo compartment 210 to achieve cooling; the heat storage component 150 applies heat to the cargo compartment 210 to achieve heating and can increase the humidity of the environment inside the cargo compartment 210. At the same time, the temperature and humidity inside the cargo compartment 210 are regulated through the cooperation of the evaporator 140 and the heat storage component 150.

[0049] Furthermore, the vehicle-mounted refrigeration device 100 also includes: a first chamber 170, which is disposed in the vehicle compartment 210 and is used to accommodate at least part of the heat storage component 150; a first air inlet 171, which is connected to the first chamber 170; a first air outlet 172, which is connected to the first chamber 170; and a first airflow driving component 173, which is disposed in either the first air inlet 171 or the first air outlet 172, and is used to drive air to flow between the first chamber 170 and the vehicle compartment 210.

[0050] For example, the vehicle-mounted cooling device 100 further includes a first chamber 170, a first air inlet 171, a first air outlet 172, and a first airflow driving component 173. The first chamber 170 is located within the vehicle compartment 210 and is used to accommodate at least a portion of the heat storage component 150. The first air inlet 171 and the first air outlet 172 communicate with the first chamber 170. The first air inlet 171 provides an inlet for air to flow into the first chamber 170, and the first air outlet 172 provides an outlet for air to flow out of the first chamber 170. Air inside can flow into the first chamber 170 through the first air inlet 171, where the heat storage component 150 heats up and flows to the carriage 210 or the outside through the first air outlet 172. At the same time, the first airflow driving component 173 is provided at either the first air inlet 171 or the first air outlet 172, and can be used to drive the air to flow between the first chamber 170 and the carriage 210. The driving efficiency can be adjusted by adjusting the state of the first airflow driving component 173, thereby adjusting the airflow rate inside the carriage 210.

[0051] Furthermore, the vehicle-mounted refrigeration device 100 also includes: a first sealing plate 174, which is disposed at the first air inlet 171 and is used to block or avoid the first air inlet 171; and / or a second sealing plate 175, which is disposed at the first air outlet 172 and is used to block or avoid the first air outlet 172.

[0052] Specifically, the vehicle-mounted refrigeration device 100 also includes a first sealing plate 174 and / or a second sealing plate 175. The first sealing plate 174 is disposed at the first air inlet 171 and is used to block or avoid the first air inlet 171. When the first sealing plate 174 is in the closed state, the air in the vehicle compartment 210 cannot enter the first chamber 170 through the first air inlet 171; when the first sealing plate 174 is in the open state, the air in the vehicle compartment 210 can enter the first chamber 170 through the first air inlet 171. The second sealing plate 175 is disposed at the first air outlet 172 and is used to block or avoid the first air outlet 172. The opening and closing of the first air outlet 172 can be controlled by the state of the second sealing plate 175. When the second sealing plate 175 is in the closed state, the air in the first chamber 170 cannot enter the carriage 210 through the first air outlet 172; when the second sealing plate 175 is in the open state, the air in the first chamber 170 can enter the carriage 210 through the first air outlet 172.

[0053] Preferably, both the first sealing plate 174 and the second sealing plate 175 can perform corresponding actions according to automatic control, and the first sealing plate 174 and the second sealing plate 175 can be sliding sealing plates.

[0054] Furthermore, the vehicle-mounted refrigeration device 100 also includes a cold storage component 160, which surrounds at least a portion of the surface of the evaporator 140. The cold storage component 160 is used to absorb and store the cold energy from the evaporator 140 and apply the cold energy to the vehicle compartment 210.

[0055] Specifically, the cold storage component 160 surrounds at least a portion of the surface of the evaporator 140 to absorb and store the cold energy from the evaporator 140 and apply the cold energy to the compartment 210, thereby achieving the effect of refrigeration.

[0056] Preferably, the cold storage component 160 can be made of a novel cold storage phase change material (DX). The novel cold storage phase change material (DX) is a high-density energy storage material. The phase change point temperature range of the novel cold storage phase change material (DX) is -30℃ to 20℃, and it has a good cold storage effect.

[0057] Furthermore, the vehicle-mounted refrigeration device 100 also includes: a second chamber 180, which is disposed in the vehicle compartment 210 and is used to accommodate at least a portion of the cold storage component 160; a second air inlet 181, which communicates with the second chamber 180; a second air outlet 182, which communicates with the second chamber 180; and a second airflow driving component 183, which is disposed in either the second air inlet 181 or the second air outlet 182, and is used to drive air to flow between the second chamber 180 and the vehicle compartment 210.

[0058] For example, the vehicle-mounted refrigeration device 100 further includes a second chamber 180, a second air inlet 181, a second air outlet 182, and a second airflow driving component 183. The second chamber 180 is located inside the vehicle compartment 210 and is used to accommodate at least part of the heat storage component 150. The second air inlet 181 and the second air outlet 182 are connected to the second chamber 180. Air inside the vehicle compartment 210 can flow into the second chamber 180 through the second air inlet 181. The heat storage component 150 in the second chamber 180 is heated and flows to the vehicle compartment 210 or the outside through the second air outlet 182. At the same time, the second airflow driving component 183 is located at either the second air inlet 181 or the second air outlet 182 and can be used to drive the air to flow between the second chamber 180 and the vehicle compartment 210. The driving efficiency can be adjusted by adjusting the state of the second airflow driving component 183, thereby adjusting the airflow rate inside the vehicle compartment 210.

[0059] Preferably, the first chamber 170 and the second chamber 180 are not directly connected to avoid conflict between the heat in the first chamber 170 and the cold in the second chamber 180, thereby reducing the storage efficiency of the heat storage component 150 and the cold storage component 160.

[0060] Furthermore, the vehicle-mounted refrigeration device 100 also includes: a third sealing plate 184, which is disposed at the second air inlet 181 and is used to block or avoid the second air inlet 181; and / or a fourth sealing plate 185, which is disposed at the second air outlet 182 and is used to block or avoid the second air outlet 182.

[0061] Specifically, the vehicle-mounted refrigeration device 100 also includes a third sealing plate 184 and / or a fourth sealing plate 185. The third sealing plate 184 is located at the second air inlet 181 and is used to block or avoid the second air inlet 181. The state of the third sealing plate 184 can control the opening and closing of the second air inlet 181. When the third sealing plate 184 is closed, the air in the vehicle compartment 210 cannot enter the second chamber 180 through the second air inlet 181. When the third sealing plate 184 is open, the air in the vehicle compartment 210 can enter the second chamber 180 through the second air inlet 181. The fourth sealing plate 185 is provided at the second air outlet 182 and is used to block or avoid the second air outlet 182. The opening and closing of the second air outlet 182 can be controlled by the state of the fourth sealing plate 185.

[0062] Preferably, both the third sealing plate 184 and the fourth sealing plate 185 can perform corresponding actions according to automatic control, and the third sealing plate 184 and the fourth sealing plate 185 can be sliding sealing plates.

[0063]

Example 2

[0064] See Figure 2 The present invention also provides a cold chain transport vehicle 200, including: a compartment 210; an on-board refrigeration device 100, wherein the evaporator 140 of the on-board refrigeration device 100 is used to apply cooling to the compartment 210, and the heat storage component 150 of the on-board refrigeration device 100 is used to apply heat to the compartment 210.

[0065] Specifically, this embodiment also provides a cold chain transport vehicle 200 including a compartment 210 and an on-board refrigeration device 100 as described in any one of the first embodiments of the present invention. The on-board refrigeration device 100 is located in the compartment 210, and therefore has all the beneficial effects of the on-board refrigeration device 100 as described in any one of the first embodiments of the present invention, which will not be repeated here.

[0066] Powered by the second drive unit, air inside the compartment 210 enters the second chamber 180 through the second air inlet 181 and flows out through the second air outlet 182. As the air flows over the surface of the cold storage component 160, heat exchange occurs between the air and the cold storage component 160, lowering the air temperature. Simultaneously, water vapor in the air condenses on the surface of the cold storage component 160. As this process continues, the moisture content and relative humidity of the air decrease. When the humidity inside the compartment 210 reaches the upper limit of the control range, the second drive unit is shut off, and the third sealing plate 184 is closed to block the second air inlet 181 of the second chamber 180; the fourth sealing plate 185 is closed to block the second air outlet 182 of the cold storage device. If the air temperature inside the compartment 210 is within the temperature control range at this time, it is not necessary to open the first chamber 170 to heat the air inside the compartment 210. If the air temperature inside the compartment is below the lower limit of the temperature control range, the first chamber 170 and the first condenser 130 are activated to heat the air inside the compartment 210. Specifically, the first drive component is activated, and the first sealing plate 174 is activated to open the first air inlet 171 of the first chamber 170; the second sealing plate 175 is activated to open the first air outlet 172 of the first chamber 170. Through this process, the humidity is regulated first, followed by the temperature.

[0067] Under the power of the first drive component, air inside the compartment 210 enters the first chamber 170 through the first air inlet 171 and then flows out from the first air outlet 172. When the air flows over the surface of the heat storage component 150, heat exchange occurs between the air and the heat storage component 150, the air temperature rises, and the relative humidity of the air decreases. When the air temperature inside the compartment 210 approaches the upper limit of the temperature control, the operation of the first drive component is shut off, and the first sealing plate 174 is closed to block the first air inlet 171 of the first chamber 170; the second sealing plate 175 is closed to block the first air outlet 172 of the first chamber 170.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
