Document Type and Number:
WIPO Patent Application WO/2016/150198
Kind Code:
A1
Abstract:
Disclosed is a passive refrigeration air conditioning system for a main control room of a nuclear power plant, comprising a compressor (110), a compressed air storage tank (120), a relief pressure valve (130), and an air expander (140) which are successively connected and provided outside the main control room, and an air supply assembly (150) provided inside the main control room. The air supply assembly (150) comprises an air supply pipeline (151), and a flow control valve (153) and an isolation valve (154) which are successively provided on the air supply pipeline. Two ends of the air supply pipeline (151) are respectively connected to the air expander (140) and an emergency air supply pipe of the main control room, and the flow control valve (153) is close to the air expander (140). The present system is able to adjust the temperature of the main control room without depending on an outer power source and outer power to allow an operator to stay in the main control room and ensure a safe and reliable operation of equipment in the main control room. Moreover, the device is simplified, has a convenient installation, and can be applied to building a nuclear power plant and improving an in-service power plant, and has a lower manufacturing cost.
