Fig. 1 gives a kind of centralized domestic hot-water supply system suitable for building in the north.In this example, heating water tank 5
Desired temperature be 60 DEG C, the temperature of constant temperature water tank 6 must not than heating water tank desired temperature down to more than 8 DEG C, so, perseverance
The temperature range that reservoir 6 is set are as follows: 52 DEG C -60 DEG C.
When operation, for northern area, outside Heating Period, ambient temperature is higher, and heat pump switching valve 46 is turned off manually, connects
Electrified regulation device 52, running water switch valve 31 is normally open, using solar thermal collector 2 by the tap water in heating water tank 5
Heating, at this point, water temperature signal is reached computer control dress by the heating temperature collector 57 for being set to 5 hot-water outlet 56 of heating water tank
13 are set, when reaching 60 DEG C of setting value such as temperature, Computer Control Unit 13 automatically controls heat circulation pump 50 and passes through hot-water outlet pipe
58 store hot water to constant temperature water tank 6.
If 5 water temperature of heating water tank does not reach setting value, Computer Control Unit 13 is by 52 pairs of heating water of opening electric heater
Water in case is heated；When it reaches 60 DEG C of set temperature, Computer Control Unit 13 closes electric heater 52, and opens
Heat circulation pump 50 conveys hot water to constant temperature water tank 6.The thermostat temperature acquisition that user's hot water outlet 61 of constant temperature water tank 6 connects
Water temperature signal is reached Computer Control Unit 13 by device 64, when temperature reaches 52 DEG C -60 DEG C of temperature range of setting, computer
Control device 13 then opens user's taps valve 71, and 9 user of Xiang Loudong provides domestic hot-water.When temperature of the thermostat temperature lower than setting
When spending range, Computer Control Unit 13 controls extraction cycle pump 60 and the hot water circuit of constant temperature water tank 6 is back to heating water tank 5,
It is heated again, when 5 water temperature of heating water tank reaches setting value, the above-mentioned heat circulation pump 50 of repetition passes through hot-water outlet pipe 58 for hot water
It stores to the operation of constant temperature water tank 6, until constant temperature water tank 6 reaches the temperature range of setting, turns off extraction cycle pump 60, and open
Family taps valve 71 is enabled, Xiang Loudong user provides domestic hot-water.
In northern area Heating Period, electric heater 52 is disconnected manually, since ambient temperature is low, only leans on solar energy collection
Hot device 2 heats, and the exit water temperature of heating water tank 5 is extremely difficult to 60 DEG C of setting value, therefore heat circulation pump 50 does not work, out hot water
Pipe 58 is in an off state.At this point, opening heat pump system switching valve 46, heat pump 4 replaces the function of electric heater 52, will heat water
