针对亚热带地区冰箱、冷柜等小型制冷装置型式测试内环境的精确调控要求，设计制造了可同时产生10℃左右冷冻水和55℃左右热水的冷热水联供调控系统。利用模糊变频调控冷热水流量的方法对温度参数进行精确调控，利用冷冻除湿、旁路超声波加湿方法对湿度进行控制，设计建设了双室各八工位冰箱、冷柜型式测试室。系统运行结果表明：该系统在华南地区既可靠地满足了冰箱、冷柜型式测试室内环境对温湿度的调控要求，也实现了节能及降低投资的目的。

Aiming at the requirement of temperature and humidity precise regulation in performance testing chamber at subtropical zone for small refrigerating equipment as refrigerator and freezer etc., the new regulation system with cold and hot water combing supply from air source heat bump units which can product 10℃cold water and 55℃hot water was de-signed and manufactured specially. Using fuzzy control method by variable-frequency to regulate the hot or cold water flow, the temperature was regulated precisely. Using freezing dehumidify method and shunting ultrasonic humidifier, the humidity was controlled. Basing on these measure, double internal environment chamber having eight-station for small refrigerating equipment was built. The operating results indicated that the system not only satisfied the requirement of temperature and humidity precise regulation in internal environment chamber at subtropical zone for small refrigerating equipment consider-ably, but also realized saving on electricity and the amount of investment.
