Application research of LNG gasification cold energy to building air conditioning systems

In order to solve the waste problem of cold energy in LNG gasification, puts forward a scheme that the cold energy in LNG gasification can be recovered by ice cool storage as the cold source of air conditioning system in surrounding buildings. Taking the air conditioning system of a service building (peak load of 3 140 kW) around a LNG gasification station as an example, analyses the equipment initial investment and operation cost of the conventional air conditioning system and the LNG gasification cold energy recovery system. The results show that with the local peak-valley electricity price, the recovery of gasification cold energy is about 2.725 million kWh, the operation cost of the latter is reduced by about 538 400 yuan, and the static investment payback period is 1.7 years.
