Ceiling and wall coolers
In refrigeration systems with a required cooling capacity from several hundred W to over a dozen kW evaporators (heat exchangers) with forced air movement are used. These are called fan air coolers. In the closed casing there is a lamellar evaporator and from one to several axial fans causing increased airflow to increase the efficiency of the heat transfer between the cooled medium and the cooling medium (usually refrigerant, glycol or water). For cooling rooms and refrigerated furniture with a target temperature below 2 ° C, the radiators are also equipped with an electric heater for defrosting. Depending on the method of fixing, we distinguish the ceiling and wall coolers.
