PURPOSE:To produce the hot water of high temperature and hot water of intermediate temperature, by a method wherein a heated refrigerant vapor discharged from a compressor for a heat pump which vapor is a high-temperature gas of a temperature of higher than 100 deg.C is utitlized to produce hot water of the high temperature at about 80 deg.C in a heated vapor region, and the mixed gas of intermediate temperature (about 60 deg.C) obtained after heat exchange is used to produce hot water of intermediate temperature of about 55 deg.C. CONSTITUTION:The refrigerant made to be high-temperature high-pressure gas by a compressor 4 releases its heat to hot water 12 in a first condenser 10a to be intermediate-temperature high-pressure mixed gas. Therefore, hot water present in the vicinity of the condenser 10a and thereabove attains the high temperature of about 80 deg.C, whereby a high-temperature hot water region is provided at an upper part of a hot water storing tank 9. The mixed gas discharged from the first condenser 10a releases its heat in the second condenser 10b to hot water 12 present at a lower part of the tank 9 to be intermediate-temperature high-pressure liquid refrigerant. Therefore, hot water present at the lower part of the tank 9 attains the intermediate temperature of about 55 deg.C to provide an intermediate-temperature hot water region. Accordingly, since the high-temperature hot water region and the intermediate-temperature hot water region are provided in the tank 9, high-temperature hot water and intermediate-temperature hot water can be taken out respectively through a high-temperature hot water supplying pipe 11a provided at the upper part of the tank 9 and an intermediate-temperature hot water supplying pipe 11b. |
