Dynamic ice cold storing and refrigerating equipment

Abstract

The invention relates to dynamic ice cold storing and refrigerating equipment which comprises a refrigerating unit, an evaporator and an ice storing tank, wherein an air return pipe, a hot air pipe and a liquid supply pipe of the refrigerating unit are respectively communicated with the evaporator; an air return constant pressure electromagnetic valve is arranged on the air return pipe; a hot Freon electromagnetic valve is arranged on the hot air pipe, and a liquid supply electromagnetic valve is arranged on the liquid supply pipe; a refrigerant flow channel is arranged in the a sheet of the evaporator; the evaporator is installed on the top of the ice storing tank; a temperature sensor, a high-material level switch and a low-material level switch are installed on the ice storing tank; aninternal circulating pump which can transmit water in the ice storing tank to the top of the evaporator is installed outside the ice storing tank; an air-conditioning water outlet pipe and an air-conditioning water return pipe are connected to the ice storing tank; an air-conditioning water outlet pump is arranged on the air-conditioning water outlet pipe; a temperature proportion adjusting valveis arranged between the air-conditioning water outlet pipe and the air-conditioning water return pipe; and the air-conditioning water return pipe is communicated with a circulating water pipe. The invention has dynamic ice making and storing mode, flexible running, icing thickness of 5-15 mm, good heat transfer effect, high ice making efficiency, large cold storing amount, small occupation area and low cost.

Description

technical field [0001] The invention relates to the technical field of ice storage equipment, in particular to a dynamic ice storage refrigeration equipment. Background technique [0002] The ice-storage air-conditioning system makes ice by using cheap electricity during the low-load period of the power grid at night. When the power supply of the power grid is tense during the day, the operation of the refrigeration unit is stopped. Cooling places. Shifting peaks and filling valleys means alleviating the tension of power grid power supply, and using cheap electricity at night to save the overall operating cost of air-conditioning and refrigeration units, so it has developed rapidly around the world. [0003] At present, the ice storage central air-conditioning system mainly adopts "ice hockey" and "ice coil" cold storage systems. [0004] Ice hockey cold storage system introduction: The outer surface of the ice hockey is made of polyethylene, and the shape is a ball with a...
