Research and development program of gas driven heat pumps for domestic use in Japan.

Author(s) : HONDA T., YOSHIDA S.

Summary

The Japan Gas Association has commenced an R&D program focusing on small-sized gas driven heat pumps for domestic use supported by the Government, and plans to proceed with this research and development jointly with four gas utilities and 11 HVAC manufacturers. The heat pumps to be developed are required to be operated in both cooling and heating mode, and their cooling capacities range from 2.5 to 7.0 kilowatts. The purposes of the R&D are to reduce the initial cost by minimizing the size and weight of the heat pumps, and to attain freedom from maintenance by means of air cooling. Four different systems are to be developed, including absorption chiller-heaters using water-lithium bromide, absorption chiller-heaters using ammonia-water, a gas engine driven heat pump and a Vuilleumier cycle heat pump.
