A heating system has a heat pump combined with solar heating which is enhanced during winter months by the absorption fluid

摘要

The generator powered compressor (1-2) has a condenser (2-3) providing heating, an expansion valve (3-4) and evaporator (4-5) providing cooling leading to an ammonia absorber in which rich solution (I) is pumped (II) through the solar panel and returned (III) as a weak solution is expanded and returned (IV) to the absorber and refrigerant to the compressor.
