On the oil platforms in the Bohai Sea, when air-cooling air conditioners run at low temperature, problems such as hard to start, hard to run in steady condition and high energy consumption etc. may appear. Although fresh air duct type air conditioners can solve the problem of low-temperature refrigeration in room, they also have some problems such as large area occupation, high indoor temperature fluctuation and poor comfortableness. We introduce the system composition, working principle and technical features of low-temperature refrigeration liquid pump energy-saving technology, and analyze its energy-saving principle. This technology could provide a new solution to the low-temperature refrigerating problem in electric room of Bohai Sea platforms.
