Abstract: PURPOSE:The hot-water feeding apparatus which utilizes the waste-heat of a condenser, and in which high-temperature water is obtained by using a plural number of coolant having different saturation temperatures, in mixing. CONSTITUTION:A coolant such as flon-22 which has a low saturation temperature corresponding to refrigerating action and a coolant such as flon-C318 which has a high saturation temperature corresponding to water-heating action are mixed. As to the coolant having been discharged from a compressor 1 equipped with coolant injection type cooling apparatus, only flon-C318 having a high saturation temperature condenses in the heat exchanger 3 in a high temperature water tank 2, and the condensed liquid of flon-C318 having been separated in a gas-liquid separator 4 returns to the compressor 1 and is jetted to cool the compressor 1. The gas of flon-22 having been separated in the gas-liquid separator 4 is cooled by the heat exchanger 7 in a medium temperature water tank 6, and condenses in a main condenser 8, and returns to the compressor 1 through a throttle 9 and an evaporator 10.

Abstract: PURPOSE:To easily provide hot water at medium and high temperatures as occasion needs, by using a compressor having two discharge pipes of ordinary and high pressures. CONSTITUTION:A compressor used for this system has two kinds of discharge pipes: an ordinary pressure pipe 2 connected with a heat exchanger 5 in a medium temperature tank 4 and a high pressure pipe 3 connected with a heat exchanger 12 in a high temperature tank 11. Hot temperature gas from the ordinary pressure discharge pipe 2 heats water in the medium temperature tank 4, the water level of which is kept constant by means of a float vlave 15, to produce medium temperature water, and part of the hot water is fed through a water pipe 17 in the high pressure tank 11 where the water temperature is raised by high temperature gas from the high pressure discharge pipe 3 to quickly supply domestic hot water.
