Detailed description of the invention
Below in conjunction with accompanying drawing, most preferred embodiment of the present invention is described in detail.
As shown in Figure 1, energy-conservation Cooling and Heat Source water system comprises cooling water pump 1, condenser 2, triple valve 3, cooling tower 4, cold water temperature control water pump 5, cold water storage cistern 6, mixing tank 7, boiler 8, chilled water water pump 9, evaporimeter 10, hot water controller 11, boiler temperature sensor 12, cold water controller 13, cold water storage cistern temperature sensor 14, water source heat pump units.
Water source heat pump units is a kind of heat absorption heating equipment, and a side of its heat absorption produces low temperature, heats a side and produces high temperature, and evaporimeter (10) is arranged on the refrigeration side of water source heat pump units, and condenser (2) is arranged on the side that heats of water source heat pump units.
Cold water storage cistern 6, mixing tank 7, boiler 8 are arranged side by side from high to lower, cold water storage cistern 6 arranges cold water overfall, cold water overfall is communicated with mixing tank 7, mixing tank 7 arranges mixing water overfall, mixing water overfall is communicated with boiler 8, boiler 8, cold water temperature control water pump 5, cold water storage cistern 6 are communicated with successively, and cold water storage cistern temperature sensor 14 is arranged in cold water storage cistern 6, and cold water controller 13 is electrically connected with cold water storage cistern temperature sensor 14 and cold water temperature control water pump 5 respectively.
Cold water storage cistern 6, chilled water water pump 9, evaporimeter 10 successively head and the tail are communicated with;
Boiler 8, cooling water pump 1, condenser 2 and triple valve 3 successively head and the tail are communicated with, a wherein port of triple valve 3 is communicated with the hot water water inlet of cooling tower 4, the cold water delivery port of cooling tower 4 is communicated with mixing tank 7, boiler temperature sensor 12 is arranged in boiler 8, and hot water controller 11 is electrically connected with boiler temperature sensor 12 and triple valve 3 respectively.
Cold water storage cistern 6 is provided with independently cold water delivery outlet, and boiler 8 is provided with independently hot water output port, and mixing tank 7 is provided with independently mixing water delivery outlet.
Operation principle: evaporimeter 10 is walked the heat absorption of cold water storage cistern, makes the water temperature of cold water storage cistern low, and condenser 2 release heat, to boiler, make the water temperature of boiler high; Thereby it is poor to utilize heat pump principle to realize two water tanks generation product potential energies.
When the water temperature of cold water storage cistern 6 lower than set threshold values time (by cold water storage cistern temperature sensor 14 detected temperatures, temperature signal sends cold water controller 13 to and does to judge), cold water controller 13 is withdrawn into cold water storage cistern by starting cold water temperature control water pump 5 appropriate hot water, realize the temperature control of cold water storage cistern 6, when cold water storage cistern 6 hypervolia, the water having more flows out from the cold water overfall of cold water storage cistern 6, flows to mixing tank 7.
Triple valve 3 is diversion three-way valves, triple valve 3 is controlled the water yield ratio of getting back to boiler 8 and flowing to cooling tower 4, in the time that detecting the excess Temperature of boiler 8, boiler temperature sensor 12 (does to judge by temperature signal being sent to hot water controller 11), hot water controller 11 is controlled triple valve 3 regulating water flow ratios, control the appropriate direct bypass of water heating through condenser 2 reducing and get back to boiler, unnecessary spent hot water dissipates after heat to cooling tower 4, get back to mixing tank 7, and the mixing tank water having more meeting overflow is to boiler, because mixing tank water temperature is lower, thereby reduce boiler temperature, otherwise, if boiler temperature sensor 12 detects when the temperature of boiler 8 is too low and (does to judge by temperature signal being sent to hot water controller 11), hot water controller 11 is controlled triple valve 3 regulating water flow ratios, control the water yield that the appropriate direct bypass of water heating through condenser 2 increasing is got back to boiler, reduce cooling tower 4 heat dissipation capacities, thereby progressively improve boiler temperature,
In addition, energy-conservation Cooling and Heat Source water system disposes the necessity such as power supply, water replanishing device but known facility, and each water tank is with some water inlets, for supplying hot and cold water.Triple valve control also can be set at water inlet place and mix hot water or cold water's ratio that supplies water, realize the water supply of the arbitrary temp between cold water storage cistern and boiler temperature.
Only as described above, it is only the present invention's preferred embodiment, when not limiting with this scope of the invention process, the content of generally recording according to the claims in the present invention and description of the invention has been done simple equivalence and has been changed and modify, and is all still covered by the claims of the invention.In addition, summary part and title are only the use for auxiliary patent document search, are not used for limiting the present invention's interest field.
