Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] This embodiment provides a novel method for temperature regulation of a refrigerator with single cycle and three temperature zones independently adjustable.
[0027] Such as figure 1 As shown, the principle of the single cycle refrigerator is:
[0028] Compressor 1, condenser 2, defrosting tube 3, dry filter 4, capillary tube 5, freezer evaporator 6, variable room evaporator 7, and refrigerating room evaporator 8 are arranged in a ring in sequence, and the flow direction of the refrigerant is from Compressor 1 flows to condenser 2. The refrigerating room evaporator 8 and the variable temp...

The invention provides an independent temperature control method of a single-circulation three-temperature-zone refrigerator. According to the method, through a compensation heater of a refrigerating chamber of the refrigerator and / or a compensation heater of a variable temperature chamber, both connected with a controller of the refrigerator, compensational heating is achieved; and through NTC (negative temperature coefficient) temperature sensors in signal connection with the controller of the refrigerator and arranged in the refrigerating chamber, the variable temperature chamber and a freezing chamber and on a refrigeration evaporator and a display panel of the refrigerator, the temperature of the refrigerating chamber, the temperature of the variable temperature chamber, the temperature of the evaporator and the ambient temperature are sensed. The compensation heaters are connected with the controller of the refrigerator through a circuit. The single-circulation three-temperature-zone refrigerator allows temperatures of three temperature zones to be independently controllable, allows the temperatures to be controlled precisely and is suitable for batch production.
Description
technical field [0001] The invention relates to the technical field of refrigerators, in particular to an independent temperature control method for single-cycle three-temperature zone refrigerators. Background technique [0002] The existing single-cycle three-temperature zone refrigerator refrigeration system is formed by matching the area of the evaporator for refrigeration, variable temperature, and freezing according to a fixed ratio, so as to realize the linkage temperature regulation of the system. The defect of this kind of refrigerator is that it cannot adjust the temperature independently, and generally uses a mechanical thermostat to sense the temperature of the refrigerated evaporator to control the start and stop of the compressor. The temperature control is rough and not precise enough. Contents of the invention [0003] In view of the background technology, the object of the present invention is to provide a method for independently controlling the tempera...
