Air conditioning has also entered people’s homes. The widespread use of air conditioners has greatly improved the living standards of nationals, but in other side, it has also caused a series of energy problems. As we know, people usually use air conditioning when they feel hot. And the power consumption of air conditioning is very high. So it cause the load of electric network out-off-balance. Specifically speaking, at daytime, the electricity is lack; at night, the electricity is surplus. In this situation, the cold storage technology has appeared. As the name suggests, the cold storage technology is a technology that store cold. Specifically speaking, Is the use of electricity in electricity production of cold energy is stored in certain substances, takes those in peak cooling capacity to meet the cooling load. So it makes the cooling capacity of the production and use of separated in time, greatly reduce the burden on the network, reducing the waste of energy, and brings about considerable economic benefits for the user. This article focuses on the principles, characteristics and classification of cold storage technology, describes the current status of storage technology, analysis of cool storage technology development prospects and development direction in the future. And an office building design of a simple storage system. Keywords: cold storage technology; air condit
