Cold storage air conditioner system with test function

Abstract

The invention discloses a cold accumulation air conditioner system having test function, which comprises a refrigerant cycling system, a secondary refrigerant cycling system and an air conditioner chilled water cycling system; wherein, the refrigerant cycling system and the secondary refrigerant cycling system can interchange heat by an evaporator, the refrigerant cycling system and the air conditioner chilled water cycling system interchange heat by a heat interchanger, a preheater is internally filled with a heat transferring medium (such as water and the like), a cold accumulation barrel is internally provided with a cold accumulation ball or board which is internally encapsulated with cold accumulation materials, secondary refrigerant fluid passes through a gap flow passage outside the cold accumulation ball or board and interchanges heat with the cold accumulation materials in the cold accumulation ball or board, and refrigeration capacity is stored into the cold accumulation ball or board. The invention can be used for testing the performance of the cold accumulation air conditioner system under the working conditions of refrigeration, cold accumulation, cold release and normal cold supply, can test the low temperature air supply characteristics of the cold accumulation air conditioner system, and can test the characteristics of cold accumulation and cold release of an ice ball type or an ice plate type cold accumulation air conditioner system.

Description

technical field [0001] The invention relates to a refrigeration air conditioner, in particular to a cold storage air conditioner system with testing function. Background technique [0002] Energy saving and environmental protection are the most important issues in the field of energy utilization. Using the phase change latent heat of phase change materials to store energy (cold storage, heat storage) is a new environmental protection and energy saving technology. During the process of phase change itself, the phase change material absorbs the heat (cold) of the environment, and releases the heat (cold) to the environment when needed, so as to achieve the purpose of controlling the ambient temperature and saving energy. It has broad application prospects in refrigeration low temperature, solar energy utilization, building energy saving, heat energy recovery, aerospace and other fields. [0003] Although my country's electric power industry has made considerable progress, the...
