Take a costal hotel forexample, its total floor area is 47,879m2. The hotel has a 4 ton oil boiler and2 sets of 420KW electric boilers, and uses water chilling unit. As the fuelprice is increasing every year, the heating cost of the hotel accounts for morethan 15% of the avenue. Because the hotel is located at the seaside and part ofit is above the sea, it’s very convenient for the hotel to use sea water.Besides, the temperature of sea water is appropriate for using it as the heatsource during winter days, thus the hotel installed the sea water source heatpump system.

The sea water source heat pump system was put into use in October 2011 and gained good heating effect. The heating period is from October 15th to April 15th, and the system uses sea water as heat source when the sea water temperature is above 3℃; in the rest period, the hotel uses the fuel boiler for heating. During one heating period, the heating cost is reduced to one million Yuan from 1.7 million Yuan, which brings remarkable economic benefits.
