Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] see figure 1 , the traditional computer temperature-controlled refrigerator control system generally has the following parts: temperature sensors for detecting refrigerators, freezers, evaporators, and ambient temperatures, load components such as compressors, defrosting heaters, and solenoid valves that control refrigerant flow, The memory, the main control unit that communicates with the temperature sensing head and the load part, the main control unit generally has unit circuits such as a microprocessor and a power conversion. The refrigerator of the present invention is provided with a cold accumulator, and an air duct is set between the cold accumulator and the refrigerating room, and a fan or other air circulation device is arranged on the air duct, so that when needed, the cold stored in the cold accumulator can be operated by the fan Bri...

Abstract

A control system for refrigerator's running in time interval comprises temperature sensor, a time display unit of time interval settable ability, power circle, storage unit, clock unit and a CPU links to the above units, refrigerating circle, coolant tank and a calculator to calculate L3 from the preset temperature L1 and sensor temperature L2, a controller for different running programs according to L1, L2 and L3; a time calculator to calculate the data from clock unit and L2, L2 and L3. This invention makes it possible for the refrigerator to run more in the time interval at low power price and run less in the time interval at high power price.

Description

technical field [0001] The present invention relates to a refrigerator control technology, and more specifically relates to a control system and a control method for a refrigerator operating in different periods. Background technique [0002] According to authoritative data, in any part of the world, there are "peak", "flat peak" and "low peak" segments of electricity consumption every day, and the ratio of electricity consumption between them is more than 4:2:1. A lot of manpower and material resources have been invested in the electricity consumption demand of the "peak" section, and the same is true in our country. Our country is a country with very tight energy supply. At present, time-of-use billing electricity price policy is implemented in many areas, and the electricity price is different at different time periods every day. Ordinary refrigerators need to rely on the periodic frequent start and stop of the compressor to ensure the refrigerating / freezing temperature ...
