Rapatrier le gaz dans un compresseur de clim

If you need to move an air conditioner or make modifications to an air conditioning system, this video will show you a do-it-yourself method for recirculating refrigerant gas into the outdoor compressor. Here, the refrigerant connection was too short, and the air conditioner was noisy indoors: a fluid noise transmitted through the gas and liquid pipes... Refrigerant gas is highly polluting: never let it escape into the atmosphere... This video presents the steps and explanations for doing this without special tools. This method is shared for informational purposes, so you can appreciate the work involved. If you are not a qualified professional, you should still contact a qualified professional or company! You will also find instructions for starting a compressor in forced mode and for locating the SW button. The air conditioner to be moved here is a Hitachi Dodai, the same as the old SUMMIT. The whistling sound you can hear comes from the expansion of the refrigerant from liquid to gas in the evaporator; it is a sign of proper operation in cooling mode. However, the minimum length of 3 meters recommended by all air conditioner manufacturers is intended to prevent the phenomenon of "liquid slugging," which is destructive to the compressor valves and results from incomplete evaporation of the refrigerant in the evaporator (due to clogging, for example). Compressor manufacturers include an anti-liquid slug bottle integrated into the compressor to prevent breakage. The 3 meters of hose allow the liquid to completely evaporate before the gas is sucked into the compressor. There is also no need to start the liquid valve open (there is already pressure at the suction side, due to pressure-temperature relationship). Quick tip: To start in cold mode in winter, you can gently heat the temperature sensor on the evaporator with a hair dryer to trick the control.
