摘要：

针对传统恒温恒湿空调系统中表冷器定露点处理能耗大的缺点以及文物储藏环境温湿度一致性要求较高的特点,提出了表冷器热湿解耦节能技术以及一源多位温湿度控制技术,采用双回路表冷器热湿独立控制装置和PID分程控制方法,实现了博物馆文物储存环境中温湿度的精确控制。目前,该系统已成功应用于浙江省十余项博物馆文物保护工程中,实际节能率达到30.7%以上。

Abstract:

Relic protection requires high quality control of the temperature and relative humidity of the environment. Due to the large energy compensation caused by the fixed dew point on the cooling coil (CC) in the conventional constant temperature and humidity air-conditioning system, a decoupling method of temperature and humidity applying to the cooling coil is proposed, as well as the temperature and humidity control method for multi-zone. A new system employing a temperature and humidity independent control (THIC) device in the CC and a method of PID split-range control are developed. Experiments show that the temperature and relative humidity can be well controlled with a high precision. Now this system has been successfully applied to more than 10 relic protection projects of museums in Zhejiang province, with 30.7% energy-saving rate on average practically.

Key words: relic environment, cooling coil, temperature and humidity independent control (THIC), one source multi-zone
