Problems solved by technology

[0076] However, in the above-mentioned existing structure, for example, from the end of the full-open defrosting mode, regardless of whether the time for suspending the recirculation cooling mode is long or short, the next defrosting mode is started at the same time interval, but actually The amount of frost attached to the cooler 105 is reduced when the recirculation cooling mode is suspended for a long time
[0077] As a result, although the time of one defrosting mode is shortened, since the defrosting operation is performed when the amount of frosting is small, and the number of times of the defrosting mode per unit time is the same, there is a problem that the temperature of the storage room is raised unnecessarily.

Abstract

A refrigeration cycle comprising at least a compressor (19), an evaporator (20) and a condenser is provided inside a casing. The condenser comprises a forced-air-cooling main condenser (21), a flow passage switching valve (3) connected to the downstream side of the main condenser (21), and an auxiliary condenser connected to the downstream side of the flow passage switching valve (3). The auxiliary condenser comprises a plurality of anti-condensation pipes (1, 2) connected in parallel, and refrigerant flows in parallel to the plurality of anti-condensation pipes (1, 2) when the refrigeration cycle is operated under high load conditions.

Description

technical field [0001] The present invention relates to a refrigerator having a condenser pipe (hereinafter referred to as "dew prevention pipe") for preventing dew condensation on a wall surface, which suppresses pressure loss caused by the dew prevention pipe. [0002] In addition, the present invention also relates to a refrigerator, which has dampers for blocking cold air in the freezer compartment and the refrigerator compartment, respectively, and uses one evaporator to cool the freezer compartment and the refrigerator compartment separately, thereby improving the efficiency of the refrigeration cycle. [0003] In addition, the present invention relates to a refrigerator, and in particular, to a control for suppressing an increase in temperature in a refrigerator when defrosting by a heater is performed in a refrigerator that cools a storage compartment by using latent heat and sensible heat of frost adhering to the cooler. Background technique [0004] From the viewpo...
