Heat pipe recovery type constant-temperature and constant-humidity unit for cultural relic storehouse

Abstract

A heat pipe recovery type constant-temperature and constant-humidity unit for a cultural relic storehouse comprises an air return section, a filtering section, a precooling section, a cooling and dehumidifying section, a preheating section, a heating section, a humidifying section, an air outlet section, an outdoor unit and a heat pipe; the heat pipe is composed of a heat pipe evaporation section, a heat pipe heat insulation section and a heat pipe condensation section, the heat pipe evaporation section is arranged in the pre-cooling section, the heat pipe heat insulation section is arranged on the outer side of a unit box body, the heat pipe condensation section is arranged in the preheating section, and the cooling and dehumidifying section is connected with an outdoor unit. Through use of the heat pipe evaporation section, the dehumidifying capability of the cooling and dehumidifying section is enhanced, so that constant-humidity control of the constant-temperature and constant-humidity unit is more stable, and meanwhile, the relative humidity of air can be controlled within a lower design range; through use of the heat pipe condensation section, the energy consumption of cold and heat counteracting of a conventional constant-temperature and constant-humidity unit is reduced, the energy consumption is saved, in a word, the problems of an existing constant-temperature and constant-humidity unit of the cultural relic storehouse can be solved in a unified and coordinated mode, and the constant-temperature and constant-humidity unit has the advantages of being energy-saving, high in dehumidification capacity and small in equipment type selection.

Description

technical field [0001] The invention relates to a heat pipe recovery type constant temperature and humidity unit, which is suitable for various museum cultural relic storerooms and archives with high requirements for constant humidity control, and particularly relates to a heat pipe recovery type constant temperature and humidity unit for cultural relic storerooms . Background technique [0002] The cultural relic warehouse has higher requirements on air temperature and humidity control, especially stricter stability requirements for air humidity control. The temperature control range is 20°C to 25°C, and the control accuracy is ±1°C; the humidity control range is 35°C. %~60%, the control accuracy is ±3%RH. At present, the special constant temperature and humidity unit for the cultural relic warehouse usually adopts two dehumidification methods: one is to use cooling dehumidification, and the other is to use the rotor to dehumidify. For units using cooling and dehumidifica...
