Compression and absorption combined cold storage process and unit

Abstract

The invention provides a compression type and absorption type combined cold accumulation process and unit and belongs to the technical field of air conditioning equipment and energy accumulation equipment. The compression type and absorption type combined cold accumulation unit is structurally characterized in that an absorption type refrigeration evaporator, a compression type refrigeration evaporator, a compression type refrigeration condenser and an absorption type refrigeration absorber are sequentially arranged in the space in a barrel of the unit; the spaces of the absorption type refrigeration evaporator, the compression type refrigeration evaporator, the compression type refrigeration condenser and the absorption type refrigeration absorber in the barrel of the unit are sequentially communicated; a liquid partition plate is arranged between the compression type refrigeration evaporator and the compression type refrigeration condenser, and liquid baffles longitudinally arranged at equal intervals are arranged at the upper portion of the liquid partition plate; and the compression type refrigeration evaporator and the compression type refrigeration condenser at the two sides of the liquid baffles are communicated, and the fully-closed liquid partition plate is arranged at the lower portions of the liquid baffles. The equipment of the compression type and absorption type combined cold accumulation unit is easy and convenient to operate, and meanwhile needed cold accumulation ancillary facilities are reduced; and operation of a cold water pump, a cooling water pump and a cooling tower is not needed during cold accumulation, compression consumption is reduced, energy is saved, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment and energy storage equipment, in particular to a compression and absorption combined cold storage process and unit. Background technique [0002] There are two main ways of current cold storage: one is sensible heat storage, which stores cold by lowering the temperature of the medium. Commonly used mediums include water and brine with high enthalpy values, and the other is latent heat storage, which uses the phase change of the medium to store cold. Commonly used media are phase change materials such as ice and eutectic salt salt compounds. From the perspective of energy density, the latent heat storage is much larger than the sensible heat storage. In the application of cold storage technology, most of the forms used are cold water storage and ice storage. [0003] The operation mode of the cold storage part generally adopts different forms, but the main modes mainly include ...

Problems solved by technology

Therefore, the compression of air-conditioning consumption is the main factor causing the power company's heavy peak-shaving tasks and the shortage of compression force.

But now all cold storage parts have to be equipped with cold storage water tanks, the connecting pipes are very complicated, and the operation part is very inconvenient
