Energy-saving cold-accumulated-type refrigerating compartment

Abstract

An energy-saving cold-accumulated-type refrigerating compartment comprises the refrigerating compartment, a cold-accumulated cylinder filled with a cold-accumulated agent, a circulating pump, a heat exchanger, a temperature sensor and a control system; the cold-accumulated cylinder, the circulating pump, the heat exchanger and the temperature sensor are arranged in the refrigerating compartment; and the cold-accumulated agent in the cold-accumulated cylinder passes through the circulating pump and the heat exchanger, and returns to the cold-accumulated cylinder. The above technical scheme is adopted by the energy-saving cold-accumulated-type refrigerating compartment; after a refrigerating temperature is set, the temperature sensor senses a temperature in the refrigerating compartment, andfeeds a signal back to the control system; if the temperature is higher than a set value, the circulating pump is continuously operated, and heat exchange and temperature reduction are performed on air in the refrigerating compartment through the cold-accumulated agent in a heat exchange tube; and if the temperature is lower than the set value, the circulating pump reduces an output quantity of the cold-accumulated agent or is completely stopped, and a rotating speed of a fan is correspondingly reduced or work is stopped, until the temperature is higher than the set value. Through the above method, the cold-accumulated agent is avoided from refrigerating at any time; an energy utilization ratio is improved; and the using time of the cold-accumulated agent after replenishing cold once is prolonged.

Description

technical field [0001] The invention relates to the field of refrigeration and refrigeration, in particular to an energy-saving cold storage refrigerator compartment. Background technique [0002] Refrigerated compartments are widely used in the logistics and transportation of refrigerated products. Conventional refrigerated compartments are refrigerated by refrigeration units or cold storage plates, and there are the following problems: [0003] (1) Refrigeration through the refrigeration unit requires the vehicle to provide energy, which increases the fuel consumption or electricity consumption of the vehicle, reduces the cruising range of the transport vehicle, and cannot refrigerate the product during the shutdown process. [0004] (2) The cold storage plate is used for refrigeration, and the refrigeration temperature is uncontrollable, and it often continues to refrigerate after reaching the refrigerating temperature, which reduces the duration of refrigeration.
