<p>PURPOSE:To realize energy saving and obtain the profit of obtaining hot-water also by a method wherein water in a water heating tank is boiled by the radiation of heat of a pipeline when high-temperature refrigerant gas flows through the pipeline in the water heating tank. CONSTITUTION:The pipeline 1 of circulating refrigerant gas, which is connected to the side of a compressor C, formed with a plurality of bent sections (n), is provided in a water heating tank HT. The water heating tank HT is provided with a water feeding port 2, a water discharging port 3 and changeover valves 2', 3' opening and closing the water feeding port 2 and the water discharging port 3. On the other hand, a condenser CO is provided which is connected to the pipeline 1 in the water heating tank HT and changing the gaseous refrigerant, brought into high temperature and high pressure, into low temperature and high pressure. Accordingly, the water heating tank HT is arranged between the compressor C and the condenser CO whereby water in the water heating tank HT is boiled by the radiation of heat of the pipeline 1 when the high- temperature refrigerant gas flows through the pipeline 1, meandered in the water heating tank HT.</p> |
