Cooling apparatus for storing food in warehouse, has vaporizers for cooling two compartments by coolant, respectively, where one of vaporizers is provided for liquefaction of coolant vaporized by other vaporizer during de-icing operation
The apparatus (101) has two vaporizers for cooling two compartments e.g. cooling compartment (105) and freezing compartment (109), by a coolant, respectively. One of the vaporizers is provided for liquefaction of the coolant vaporized by the other vaporizer during de-icing operation. One of the compartments has lower target temperature than the other compartment. A separating device separates the former vaporizer from a refrigerant circuit. A temperature detector detects temperature of the vaporizers. Two non-return valves (111, 113) are provided in the refrigerant circuit of the vaporizers. The vaporizers are designed as condensers, cooling compartment vaporizers (103), freezing compartment vaporizers (107), plate-type vaporizers, slat vaporizers or roll bond vaporizers. An independent claim is also included for a method for defrosting a vaporizer in a cooling apparatus.
