Single-system direct-cooling refrigerator and auxiliary temperature control method for single-system direct-cooling refrigerator

Abstract

The invention discloses a single-system direct-cooling refrigerator and an auxiliary temperature control method for the single-system direct-cooling refrigerator. The single-system direct-cooling refrigerator comprises an indoor temperature sensor and a first heater, wherein the indoor temperature sensor is used for judging whether the refrigeration function needs to be started by acquiring the indoor temperature value in a refrigerating chamber, and the first heater is used for heating air at the position of the indoor temperature sensor. The auxiliary temperature control method for the single-system direct-cooling refrigerator comprises the steps that the environment temperature value is obtained, and whether the environment temperature value is lower than a preset low-temperature threshold value is judged; when the environment temperature value is lower than the preset low-temperature threshold value, the first heater is controlled to work. The single-system direct-cooling refrigerator and the auxiliary temperature control method for the single-system direct-cooling refrigerator have the advantages that the temperature of the refrigerating chamber is prevented from being too low, and the temperature of a variable-temperature chamber is prevented from being too high.

Description

Technical field [0001] The invention relates to the field of household appliances, and in particular to a single-system direct cooling refrigerator and an auxiliary temperature control method for a single-system direct cooling refrigerator. Background technique [0002] The single-system direct cooling refrigerator produces a cooling effect through the cooperation of a set of compressors, condensers, bile duct evaporators and throttling components. In order to cope with different storage needs, refrigerators are equipped with different storage rooms. Usually, the storage rooms are divided into freezer compartment, greenhouse and refrigerator. The bile duct evaporator is attached to the wall surface of each storage room to cool down the wall surface of each storage room to reach the required room temperature. The refrigerant circulation sequence of a single-system direct cooling refrigerator is the bile duct evaporator in the freezer compartment-the bile duct evaporator in the wa...

Problems solved by technology

[0004] However, the existing single-system direct-cooling refrigerator usually only has a room temperature sensor installed in the refrigerating room, and starts the refrigeration function when the temperature value measured by the room temperature sensor is higher than the preset high temperature threshold.

The preset control scheme of the existing refrigerator has a relatively ideal control effect at normal temperature (about 25° C.), but when the ambient temperature is low (10° C. and below), the control of the room temperature in each storage room is not ideal. Higher freezer temperatures usually result
