Phase change cold accumulation material in use for air conditioning, and preparation method

Abstract

A phase transfer cold storing material for air-conditioning is prepared from capric acid, lauric acid and tetradecane. Its preparing process includes heating capric acid and lauric acid separately to have them melted completely, forming comelted mixture of the two, heating the mixture to be melted completely and mixing with tetradecane to form the cold storing material of air-conditioning.

Description

1. Technical field [0001] The invention relates to an air conditioner cold storage material, in particular to a phase change cold storage material for an air conditioner and a preparation method thereof. 2. Background technology [0002] Energy-storage air-conditioning refers to the time when the power grid is low (and also the time when the air-conditioning load is very low), the air-conditioning host starts to cool (heat) and the energy storage device stores the cold (heat) The peak time of air conditioning load), and then release the cold (heat) to meet the needs of peak air conditioning load. [0003] At present, three cold storage methods are mainly used in cold storage air conditioners: water cold storage, ice cold storage and eutectic salt cold storage. [0004] Water storage is to use the sensible heat of the water storage temperature between 4-7°C to store cold. It can use conventional refrigeration units to realize the dual purposes of cold storage and heat storag...
