Phase change cold storage refrigerator with thermostatic chamber and control method of phase change cold storage refrigerator

Abstract

The invention discloses a phase change cold storage refrigerator with a thermostatic chamber and a control method of the phase change cold storage refrigerator. The phase change cold storage refrigerator with the thermostatic chamber comprises a condenser and a compressor. An electromagnetic four-way valve is arranged at an outlet of the condenser, a first outlet of the electromagnetic four-way valve is connected with a refrigeration capillary tube, and the refrigeration capillary tube is connected with a refrigeration evaporator and then connected into a compressor; a second outlet of the electromagnetic four-way valve is connected with the freezing capillary tube, and the freezing capillary tube is connected with the freezing evaporator; a third outlet of the electromagnetic four-way valve is connected with an electronic expansion valve, the electronic expansion valve is connected with an inlet of a phase change cold storage heat exchanger after being converged with an outlet of the freezing evaporator, and an outlet of the phase change cold storage heat exchanger is connected into a compressor. And the compressor is connected with the condenser. The phase-change heat exchanger arranged in the constant-temperature chamber is utilized, and the valve and the pipeline in the refrigerating system are matched to achieve multi-chamber refrigeration and guarantee continuous cold supply of the constant-temperature chambers at the same time.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a phase-change cold storage refrigerator with a constant temperature chamber and a control method thereof. Background technique [0002] With the improvement of living standards, in addition to meeting the most basic freezing and refrigeration needs, household refrigerators have an increasing demand for special area functions. The constant temperature zone, as a common zone function, is more and more used in the middle and high-end series refrigerators. The temperature in the constant temperature zone can be maintained near the set value with small fluctuations. It is often used to store perishable and perishable ingredients such as fruits, vegetables, and dairy products, or items that are sensitive to temperature fluctuations such as facial masks, cosmetics, and medicines. However, most refrigerators with constant temperature chambers on the market are constant temperatur...

AI Technical Summary

Problems solved by technology

However, at present, most of the refrigerators with thermostatic chambers on the market are thermostatic drawers, which are small in size and have limited storage space, and cannot cope with the severe temperature fluctuations caused by the normal start and stop of the refrigerator and the switching between rooms, and the actual constant temperature effect is poor.
