HEAT PUMP DEVICE |
摘要 |
An insulating material that tends not to hydrolyze is used to thereby provide a heat pump apparatus having long-term reliability. An electric motor (6) of a compressor (1) is fixed to a sealed container (10) and includes a stator (6s) around which a winding wire (6w) is wound through intermediation of an insulating material (7), and a rotor (6r) surrounded by the stator (6s). The insulating material (7) is a wholly aromatic liquid crystal polyester (LCP) having a molecular main chain constituted by a monomer including p-hydroxybenzoic acid (PHB) as an essential monomer and a monomer solely including benzene-ring as another monomer via an ester bond. The refrigerating machine oil has a saturated water content of 2% or less at 40 degrees C, a relative humidity of 80%, for 24 Hr. To suppress the explosive decomposition reaction of ethylene-based fluorohydrocarbon, a flame retardant is used to generate chemical species that complement active radicals that cause the decomposition reaction. |
