Embodiment Construction

[0032] The cooling device (9) of the invention comprises: a fresh food compartment (10) with a door (12) in which the product to be cooled is placed; a freezer compartment (11) with a door in which the product to be frozen is placed a compressor (1) which enables the refrigerant fluid to be compressed and circulated in the refrigeration cycle; a condenser (3) which enables the compressed refrigerant fluid to be condensed by cooling; a first evaporator (7) , which enables the fresh food compartment (10) to be cooled by evaporating the refrigerant fluid; the second evaporator (8), which enables the freezing compartment (11) to be cooled by evaporating the refrigerant fluid, and the first evaporator devices (7) connected in series; and at least one capillary tube (6), which is arranged after the condenser (3) and before the evaporators (7, 8) with respect to the flow direction of the refrigerant fluid, which makes the flow of the refrigerant fluid flow can be regulated ( figure...

Abstract

By means of the present invention, a cooling device (9) is realized, that prevents the fresh food compartment (10) to be cooled unnecessarily while the door (12) of the fresh food compartment (10) is open, that prevents formation of frost on the first evaporator (7) even when the user keeps the door (12) of the fresh food compartment (10) open frequently and / or for a long time while the compressor (1) is operating, thus decreasing the requirement of performing a special defrost cycle, furthermore that directs the refrigerant fluid only to the freezing compartment (11) while the door (12) of the fresh food compartment (10) is open during the refrigeration cycle, enabling preferably to maintain additional cooling in the freezing compartment (11), that enables the compressor (1) to be used more effectively, enabling a more effective refrigeration to be performed and hence providing energy saving.

Description

technical field [0001] The invention relates to a cooling device comprising two compartments and two evaporators. Background technique [0002] The user must store some food in a frozen state and some food in a refrigerated state. Producers of white goods have designed cooling units with two compartments in which products to be refrigerated and frozen can be placed separately, and two evaporators that provide cooling of these compartments at different temperatures by evaporating a refrigerant fluid , in order to meet the two needs of users. [0003] The user typically keeps the compartment door, such as the fresh food compartment door of this type of cooling device, open for a long period of time in order to place purchased produce therein. During this time, warm air from the external environment enters the compartment and heats up the compartment. This makes cooling less efficient. [0004] In the state of the art International Patent Application No. WO0237038, a double...
