Abstract
Description
Technical Field
[0001] This utility model relates generally to the technical field of containers, and more specifically to a container. Background Technology
[0002] When containers are used indoors, such as in a cleanroom, the temperature of the outer wall of the low-pressure pipe of the refrigeration compressor is generally lower than the ambient temperature, for example, around 25°C, when the refrigeration unit is operating. Due to the alternation of hot and cold temperatures, condensation forms on the outer wall of the low-pressure pipe. This condensation may drip down the pipe and onto the ground, making it difficult to clean. It may also flow into the compressor, affecting its performance and lifespan, and even causing safety accidents.
[0003] Therefore, there is a need to provide a container that can at least partially solve the above problems. Utility Model Content

[0032] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.
[0033] refer to Figure 1 and Figure 2This utility model provides a container. The container includes a refrigeration unit 110 and a heating element 120. The refrigeration unit 110 includes a compressor 111, an evaporator, and a low-pressure pipeline 112. The low-pressure pipeline 112 is connected between the compressor 111 and the evaporator. The heating element 120 is wound around the outer wall of the low-pressure pipeline 112.
[0034] According to this utility model, a heating belt is wrapped around the low-pressure pipeline connected between the compressor and evaporator of the refrigeration unit in the container. This uniformly heats the outer wall of the low-pressure pipeline to a temperature not lower than the ambient air temperature (e.g., 25°C), thereby preventing condensation from forming on the outer wall of the low-pressure pipeline. This reduces or prevents condensation and water accumulation in the compressor area of the container's refrigeration unit, preventing condensation from flowing into the equipment in the compressor area and causing damage or even safety accidents. This ensures the performance and service life of the compressor and improves the safety performance of the container.
[0035] Containers such as refrigerated containers are equipped with refrigeration units 110 for refrigeration. The refrigeration unit 110 can be installed in the container body, for example, in the end walls and / or side walls of the container. The container can be a sea container.
[0036] refer to Figure 1 The container may include a refrigeration unit 110, a heating element 120, a first electrical control cabinet 130, a two-core cable 140, and a second electrical control cabinet 150. The refrigeration unit 110 includes a compressor 111, an evaporator, and a low-pressure pipeline 112. The low-pressure pipeline 112 connects the suction inlet of the compressor 111 and the refrigerant outlet of the evaporator to draw low-temperature, low-pressure refrigerant into the compressor 111. During operation of the refrigeration unit 110, the refrigerant temperature in the low-pressure pipeline 112 is low, resulting in the outer wall temperature of the low-pressure pipeline 112 being lower than the ambient temperature. The heating element 120 is wrapped around the outer wall of the low-pressure pipeline 112, providing uniform heating to the outer wall. Under the heating of the heating band 120, the temperature of the outer pipe wall rises to no less than the ambient air temperature (e.g., 25°C), thereby preventing condensation from forming on the outer pipe wall of the low-pressure pipe 112. This reduces or prevents condensation and water accumulation in the compressor 111 area of the container's refrigeration unit 110, preventing condensation from flowing into the equipment in the compressor 111 area of the refrigeration unit 110 and causing damage or even safety accidents. This ensures the performance and service life of the compressor 111 and improves the safety performance of the container.
[0037] When the chiller 110 is powered on, the second electrical control cabinet 150 draws power. In some embodiments, the second electrical control cabinet 150 may be located inside the housing of the chiller 110. In other embodiments, the second electrical control cabinet 150 may be located outside the chiller 110.
[0038] One end of the 2-core cable 140 is electrically connected to the transformer 131, and the other end is electrically connected to the heating element 120. The 2-core cable 140 is electrically connected between the transformer 131 and the heating element 120. The 2-core cable 140 has a simple structure, low cost, and is easy to install and maintain. Of course, if needed and / or desired, the 2-core cable 140 can also be replaced by other suitable cables, such as 7-core cables, 4-core cables, etc.
[0039] refer to Figure 2 The first electrical control cabinet 130 may include a transformer 131, a battery 132, a circuit breaker, and a controller.
[0040] In some embodiments, transformer 131 can be electrically connected to heating band 120. Specifically, the power supply terminal of heating band 120 is electrically connected to the output interface of transformer 131 to supply power to heating band 120 through the output interface of transformer 131, thereby providing a suitable voltage to heating band 120 through transformer 131. The output interface of transformer 131 can be a 24V interface.
[0041] In some embodiments, the battery 132 may be electrically connected to the heating band 120 so that the battery 132 continues to supply power to the heating band 120 when the cooler 110 is powered off.
[0042] The chiller 110, battery 132, and transformer 131 can all be electrically connected to the second electrical control cabinet 150. The controller can be configured such that when the chiller 110 is powered on, the first electrical control cabinet 130 draws power from the second electrical control cabinet 150 and supplies power to the heating element 120 and charges the battery 132 via the transformer 131; when the chiller 110 is powered off, the battery 132 continues to supply power to the heating element 120. Thus, after the chiller 110 is powered off, the battery 132 can continue to supply power to the heating element 120, allowing the heating element 120 to continue operating for a period of time. This also prevents condensation from forming and eliminates condensation for a short period immediately after the chiller 110 is powered off.
[0043] Transformer 131 can be electrically connected to the second electrical control cabinet 150 via circuit breaker 133, thereby safely and conveniently controlling the on / off state of transformer 131 and realizing circuit protection for transformer 131. In some embodiments, when transformer 131 is overloaded, circuit breaker 133 operates, thereby effectively preventing overload operation of transformer 131, protecting transformer 131 from burnout, and realizing self-protection of transformer 131.
[0044] Transformer 131 can be configured to convert high-voltage power to low-voltage power for use in powering heating band 120. In some embodiments, chiller 110 can be electrically connected to a 380V power supply. Transformer 131 can be configured to convert 380V voltage to 24V voltage for use in powering heating band 120. In some embodiments, heating band 120 has a power rating of 5W / m.
[0045] In some embodiments, the container may also include a water collection tray disposed below the low-pressure line 112 for collecting condensate that has not been completely eliminated by heating with the heating band.
[0046] The working process of preventing condensation in a container according to a preferred embodiment of the present invention is briefly described as follows:
[0047] The chiller 110 is connected to a power source with a voltage such as 380V. The second electrical control cabinet 150 transmits the power to the first electrical control cabinet 130. The transformer 131 converts the high voltage to a low voltage, for example, converting 380V to 24V. This power is supplied to the heating element 120, which is wrapped around the low-pressure pipe 112, via a two-core cable 140. The heating element 120 heats up, causing the low-pressure pipe 112 to heat up, thereby reducing or preventing the formation of condensate. After the chiller 110 is powered off, the battery 132 continues to supply power to the heating element 120, allowing the heating element 120 to continue operating for a period of time. This also prevents and eliminates condensate formation for a short period immediately after the chiller 110 is powered off.
