Thus, the global utilization of the increasing popularity of hot/cold air conditioner becomes the mainstream trend. If we can use the household hot/cold air conditioner to generate heat pump water, it will be able to generate huge energy savings. In this paper:"A R&D of conventional four-way-valve cold/hot air conditioner integrating household hot water system ", it uses the high temperature refrigerant from compressor to heat exchange in a heat exchanger plate to produce hot water. Thereore, no matter cooling or heating function will be used; the original hot air discharged from the condenser is recovery to produce hot water. Thus, it results in big energy-saving effect and meanwhile it reduces the greenhouse effect. It can produce hot water and warm air in cold weather. If heating air is priority needs, you can turn off the water pump to reduce hot water supply and increase the warm air supply. The hot water can be used directly, or it can become preheat function of the system combined with thermal storage-type water heaters, and electric water heater, gas water heaters and solar water heaters. From this, it can reduce the cost of fuel costs, electricity or gas fees, achieve energy saving effect.
