Development of a heat pump unit using a natural refrigerant with an ice storage tank.

[In Japanese. / En japonais.]

Summary

The heat pump, which is air cooled, is incorporated with a canned motor, a new lubricant oil which is soluble, an electronic expansion valve and a refrigerant leak prevention system as some of the new development technologies. Two heat pump systems each with a 11 kW motor were constructed and tested for one and a half years with satisfactory results on cooling and heating performances as well as safety and reliability.
