Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated vehicles, in particular to a dual-temperature and dual-control refrigerated vehicle air-conditioning unit. Background Art

[0002] The air conditioning unit of a refrigerated truck is a non-independent refrigeration unit, which is driven by the car engine. The structure of the air conditioning unit is integral and the installation form of the air conditioning unit is front-mounted. The air conditioning unit of a refrigerated truck is a special air conditioning equipment that provides fresh air that has been filtered, pressurized, dehumidified and cooled (or heated) to the cabin of a parked refrigerated truck. It is usually composed of an evaporator and a condenser.

[0003] The bumps generated by the refrigerated truck and the operation of the air-conditioning unit itself will cause the refrigerated truck air-conditioning unit to vibrate and bump. Abnormal vibration and bumping may cause it to overturn or be damaged, affecting its normal use. Modern refrigerated truck air-conditioning units mostly use shock-absorbing brackets, which can provide shock-absorbing and buffering protection for the air-conditioning unit. However, the unit does not have the effect of automatically reminding users of abnormal vibration and bumping during operation. Utility Model Content

When the device is running, the refrigeration component generates cold air and dissipates heat to the unit. The air outlet component sends the cold air into the refrigerated truck. The supporting plate and the spring buffer and shock-absorb the device. When the device is working normally, the current of the installed battery flows out from the positive pole through the installed resistor and directly returns to the negative pole through the main line. The alarm light is in the non-working state. When the device vibrates abnormally, the blocking plate vibrates up and down with the vibration of the supporting plate, and the amplitude increases, and it contacts the branch line below and cuts it off. The current of the installed battery will pass through the branch line, causing the alarm light to sound a warning to remind the staff that the air-conditioning unit is in an abnormal working state at this time.

[0016] The protective plate and the protective frame are set on the outside of the air outlet component to protect the air outlet component. When the air outlet component is working normally, the current of the protective battery directly returns to the protective battery through the protective resistor and the protective frame, and the protective light is in a non-working state. When the air outlet component is collided or squeezed by unsecured objects in the refrigerated truck, the protective frame will be damaged first, and the current of the protective battery will pass through the protective branch line, causing the protective light to issue a warning to remind the staff that the air outlet component may be damaged by collision or squeezing, and needs to stop for inspection.
