Dynamic energy storage and cooling integrated refrigeration energy-saving system and control method thereof

Abstract

The invention discloses a dynamic energy storage and cooling integrated refrigeration energy-saving system and a control method thereof. Through a common compression condensation module, the system creatively adopts two types of evaporators and two types of secondary refrigerants of chilled water and ice slurry solution on one air conditioner main machine, a coupling control method of a time controller, a temperature sensor and a liquid level transmitter is adopted, the mode that a combined type throttling device directly exchanges heat with ice slurry is combined, so that conventional refrigeration and efficient dynamic energy storage and cooling integrated operation is realized. According to the system, the condition that an existing refrigerating unit cannot simultaneously realize conventional refrigeration and dynamic energy storage and cooling is effectively solved, a user can be helped to realize two purposes of one machine, the repeated investment of user refrigeration equipment is saved, the energy storage and cooling efficiency is improved, so that the investment and the use cost of an air conditioner can be saved for the user, and the system can be widely applied to the field of energy saving of the air conditioner.

Description

technical field [0001] The invention relates to a dynamic energy storage and cooling integrated refrigeration energy-saving system and a control method thereof, and relates to the technical field of air-conditioning refrigeration energy conservation. Background technique [0002] At present, air conditioning energy storage is widely used: the main application methods are as follows: [0003] The user adopts two different working conditions of the air conditioner: conventional air conditioner and cold storage air conditioner: the conventional air conditioner is used in the power valley or flat period, and directly provides chilled water with a temperature of 7°C or above to provide cooling to the user. The cold storage air conditioner is used during the power valley period to store energy and provide cooling capacity to users during the daytime power peak or flat period. At this time, the main unit of the air conditioner is not turned on, so as to achieve the purpose of shift...

AI Technical Summary

Problems solved by technology

If the complete cold storage method is adopted, due to the low COP of the refrigeration main engine under the cold storage working condition, the power price difference between the flat section and the valley section is not obvious, and it is not economical to supply the flat section for cooling after cold storage;
