Why does it take 3 minutes to start the refrigeration compressor after shutdown? 2 branches do not work? Please teach seniors!
The four floor of the horse a nice shot! I admire!
The compressor will snow by pressure to high pressure pipeline (at the outlet of the compressor and a check device. This is also part of the pipeline heat pipe), and then through the throttle (also called capillary pipe throttling) sprayed into the low-pressure pipeline (indoor refrigeration pipeline), and then return to the compressor.I imagine a very thick pipe in an indirect fine tube is connected with a thick pipe, the water in the pipeline in the front is not blocked because the tube will have a lot of pressure (behind because of continuous pressure, and a non-return device)? But in capillary tube end because a small amount of water in capillary flow, and the pressure will become very low? The answer is not to say yes or no.After the compressor stops, because the throttle, the refrigerant pipeline cannot immediately return to the compressor, this process is about 3~5 minutes. If you immediately start the compressor, and the residual in the refrigerant line, because of negative force, the opportunity to reduce starting current strong at the moment, so that the compressor produces high temperature, compressor protection circuit the power supply is automatically cut off. If bad luck, the coil in the strong current moment might burn down the compressor.Louzhu asked 2 branches can not, nor is not, for your compressor longevity, it is better to boot after 3~5 minutes
Small refrigeration equipment usually needs to be delayed, as the first floor says. But large refrigeration equipment should pay attention to the pressure at the low end, low pressure may occur when the liquid hit phenomenon. Therefore, the delay time is not the main, the main is high and low pressure should be within the control range.
