Rinse Foaming Cleanser Away With Garden Hose
Since no condensate is formed on the outdoor coil when the unit is run, it will need to be rinsed manually. Do not force a direct a stream of water into the coils, but merely allow the foam to float away as the water is allowed to flow over the coils.
In the refrigeration cycle, heat is transported from a colder location to a hotter area. As heat would naturally flow in the opposite direction, work is required to achieve this.
A refrigerator is an example of such a system, as it transports the heat out of the interior and into its environment. The refrigerant is used as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.
Circulating refrigerant vapor enters the compressor, where its pressure and temperature are increased. The hot, compressed refrigerant vapor is now at a temperature and pressure at which it can be condensed and is routed through a condenser.
Here it is cooled by air flowing across the condenser coils and condensed into a liquid. Thus, the circulating refrigerant removes heat from the system and the heat is carried away by the air.
The removal of this heat can be greatly augmented by pouring water over the condenser coils, making it much cooler when it hits the expansion valve. The condensed, pressurized, and still usually somewhat hot liquid refrigerant is next routed through an expansion valve (often nothing more than a pinhole in the system’s copper tubing) where it undergoes an abrupt reduction in pressure.
