Is it normal for the compressor to be hot when the walk-in constant temperature and humidity room is running?

The walk-in constant temperature and humidity room, as a simulated environmental test equipment, has cooling and heating functions, and its cooling function is the main core accessory. Recently, a customer asked this question: Is it normal for the compressor to become hot when the walk-in constant temperature and humidity room is running?

The refrigeration system generally uses German Bitzer compressors for walk-in constant temperature and humidity rooms, which are air-cooled and water-cooled. In order to save time and reduce noise, water-cooled compressors are used for cooling. Due to long-term work, the compressor unit sometimes has some failures, or some failures occur due to improper operation, resulting in the compressor unit not being cooled.

The walk-in constant temperature and humidity room is mainly aimed at the adaptability test of large-scale electrical and electronic products, as well as their components and other materials in high temperature, low temperature, and high and low temperature damp and heat alternating environments. Used in product design, improvement, identification and inspection.

The walk-in constant temperature and humidity room can control the heating and cooling rate within the range of the cooling rate capability, that is, the heating and cooling rate can be controlled according to the slope of the set curve.

Our technicians explained that it is normal. The compressor needs output power to cause external heating, but if the compressor cools down slowly, it is abnormal. The internal parts are worn for a long time, especially the exhaust valve. Generally speaking, the machine is a bit hard to work, and the insulation is not good. Therefore, the surrounding environment of the walk-in aging test room is very strict, and it needs to be far away from the heat source area, such as "unventilated places, places exposed to direct sunlight". Hygienic surroundings, reasonable placement of samples inside the test chamber, timely defrosting, and reducing the number of door openings are all methods of maintaining the walk-in aging test chamber.

The production of a walk-in constant temperature and humidity room needs to consider whether it can meet the requirements of the user’s goal, whether various environmental factors are taken into consideration, and the effects of cooling, heating, humidification, and dehumidification must be achieved, so in the design and selection At the same time, its control ability must be large enough, but also a little margin, which is crucial.
