Ice-slurry cooling-based ice-storage air-conditioning unit

Abstract

The invention discloses an ice-slurry cooling-based ice-storage air-conditioning unit, relates to an ice-storage air-conditioning unit adopting a new ice-slurry preparation method and directly supplying cold to the tail end (a fan coil or an air-conditioning box) of an air conditioner by using the ice-slurry as a cold containing fluid, and belongs to a cooling air-conditioning system. To solve the problems of low efficiency, large primary investment and the like in the conventional ice-storage air-conditioning unit, the invention provides a novel high-efficient ice-slurry cooling-based ice-storage air-conditioning unit which directly supplies cold to the fan coil or the air-conditioning box by using the ice-slurry as a cold containing fluid. The air-conditioning unit comprises an ice-slurry loop and a cooling loop, wherein the ice-slurry loop comprises an ice machine (1), an ice crushing barrel (2), a No.1 pump (3), an ice storage tank (4), a flow control valve (5), a mixing pool (6), a No.2 pump (7) and related connecting pipelines thereof; and the cooling loop comprises the mixing pool (6), a No.3 pump (8), the tail end of a first air-conditioner (9), the tail end of an n air-conditioner (10) and related connecting pipelines thereof.

Description

technical field [0001] The invention relates to a new preparation method of liquid ice, and realizes the ice-storage air-conditioning unit that uses liquid ice as a cooling fluid to directly supply cooling to the end of the air conditioner (fan coil or air-conditioning box), and belongs to the refrigeration and air-conditioning system. Especially the technical field of ice storage air conditioning system design and manufacture. Background technique [0002] Ice storage technology, as a new technology that can realize peak-filling of electricity consumption, increase the power load rate of the power grid, and at the same time greatly reduce the installed capacity of chillers in air-conditioning systems, has been applied in more and more occasions. At present, conventional ice storage methods mainly use solutions such as ethylene glycol as the freezing medium. During cold storage, the ethylene glycol solution absorbs cold energy from the evaporator of the refrigeration unit, a...
