宽温型中央空调机组冷凝压力的控制方法

Control method of condensation pressure of central air-conditioning unit with wide temperature scope

为实现宽温环境下中央空调冷凝压力处于安全范围及冷凝风机和冷凝器电磁阀不频繁动作的双重设计目标,通过对实际空调系统进行多工况测试,指出宽温型中央空调机组冷凝压力最佳控制方法为冷凝风机在安全压力范围内需全程运行,冷凝器电磁阀压力控制区间需大于每个电磁阀通断对设备所造成的冷凝压力变化值。

Aimed at the design of both condensation pressure kept at safety scope and solenoid valves of condenser fan and condenser without frequent action for the central airconditioning under wide temperature scope,through testing the actual air-conditioning system under various operation conditions,it＇s pointed out that the best control method of condensation pressure of central air-conditioning unit with wide temperature scope is to keep condenser fan running for whole course within a safe pressure scope,and control section of condenser＇s solenoid valve pressure wider than each change valve of condensation pressure caused by switching solenoid valves.
