在空调通风系统中,因电加热原因而引起火灾事故的事例时有发生,系统中的高、中效空气过滤器,也有因缺少压差报警仪表,而不能及时地对过滤器进行清洗或更换,造成了阻力过大,能耗增加。中国建研院空调所和浙江东阳节能仪表厂联合研制的CYM-10型风速开关,是解决以上问题的一种膜盒式 In the air-conditioning ventilation system, the occurrence of fire accidents due to electrical heating has occurred from time to time. The high- and medium-efficiency air filters in the system and the lack of differential pressure alarm instruments can not timely clean or replace the filter. , resulting in excessive resistance and increased energy consumption. The CYM-10 wind speed switch jointly developed by the China Institute of Building Air-Conditioning and the Zhejiang Dongyang Energy-Saving Instrument Factory is a membrane cassette type that solves the above problems.
