Native system is made of three big systems: summer heating, summer refrigeration system, the system of winter heating.These three systems are not independently, are complementary on the technology between them, and equipment is shared, in fact be exactly three independently technology finish with a cover system equipment.Cooling and Heat Source and cooling thermal medium all are pure water.
Summer heating
Summer, the user was except the needs cooling, also needed domestic hot-water supply, as had a bath etc., and if the user cook, boil water with the hot water that native system provides, also can save a lot of energy.Summer, the core of heating was a hot water storage tank 300.The pure water circuit of this hot water storage tank 300 and three closures is connected.At first, be connected with the low-temperature receiver loop of heat pump 100, if the low-temperature receiver coolant-temperature gage that heat pump 100 comes out is than higher, can be used to heat the cold water of hot water storage tank 300, can accumulation of heat judge by two temperature sensors, when temperature sensor determines 182>numbers sensors 181 of No. two sensors, illustrate that hot water that heat pump 100 comes out can not the feed-tank accumulation of heat, robot control system(RCS) can be closed No. two switch valves 1502, No. three switch valves 1503, open switch valve 1501 No. one, forbid that the low heat pump of temperature 100 hot water enter hot water storage tank 300.Next is a solar thermal collector 500, and daytime in summer, solar energy directly is used for heating the water of 300 li of hot water storage tanks.By No. three pumps 113 water in the water tank is circulated in 300 these loops at solar thermal collector 500, hot water storage tank.Constantly solar energy collecting in hot water storage tank 300, but solar energy is a kind of very unsettled energy, whether the utility model is controlled this system automatically and is moved by No. five sensors 185, No. six 186 two temperature sensors of sensor.When 186>No. five sensors 185 of No. six sensors, illustrate that solar energy can also be stored into hot water storage tank 300, when 186<=No. five sensors 185 of No. six sensors, explanation can not be hot water storage tank 300 accumulation of heats, robot control system(RCS) can be closed this system automatically, stop pump 113 No. three, close No. six switch valves 1506, No. seven switch valves 1507.The loop that last loop is made up of electric heater 700 and hot water storage tank 300.This is one and ensures the loop, when system detects the hot water temperature who is sent to the user and does not reach setting value by No. four sensors 184, system will start electric heating system automatically, keep closing 1513, ten No. four switch valves 1514 of ten No. three switch valves, open 1516, ten No. eight switch valves 1518 of ten No. six switch valves and No. four pumps 114.In addition,, can calculate and to hold how many heats evening, could guarantee firmly not drive electric heater 700 daytime,, save cost so that use electricity in off-peak hours by the reference record analytical system of robot control system(RCS).
Summer refrigeration system
It is conventional heat pump 100 that native system provides idle call cold, nucleus equipment summer.The cooling medium is a pure water, and the cooling water that comes out at heat pump 100 is stored in accumulation of energy water tank 800 (also can be called the cold-storage water tank) earlier, delivers to the user again, returns heat pump 100 then.Utilize cold-storage water tank 800, can make full use of cheap low ebb electricity, save cost.The low-temperature receiver loop feature comprise hot water storage tank 300, hot coil 400, solar thermal collector 500, cooling tower 600.According to circumstances difference in process of refrigerastion, the low-temperature receiver loop is according to the difference of situation, and the path of being walked is different, and its principle is energy-conservation to greatest extent.Hot water by heat pump 100 comes out judges whether to enter hot water storage tank 300 through a sensor 181 and 182 two temperature sensors of No. two sensors.When 182<numbers sensors 181 of No. two sensors, that just explanation hot water storage tank 300 is had heat release, keeps No. two switch valves 1502, No. three switch valve 1503 valves to open switch valve 1501 passes.When 182>=numbers sensors 181 of No. two sensors, illustrate that the hot water that heat pump 100 comes out can not be to hot water storage tank 300 heat releases, No. two switch valves 1502, No. three switch valves 1503 are closed, and No. one switch valve 1501 is opened.The low-temperature receiver water thermostat layer that is driven underground afterwards, because the thermostat layer temperature is local annual mean temperature, thus lower than atmospheric temperature during freezing, desirable constant temperature low-temperature receiver can be provided.Low-temperature receiver water is delivered to solar thermal collector 500 after thermostat layer is cooled out.When solar energy was not hot water storage tank 300 accumulation of heats, low-temperature receiver water entered 500, No. five switch valves of solar thermal collector 1505, No. six switch valves 1506 are opened, and No. nine switch valve 1509 closes.Purpose is to utilize the performance of its heat radiation, judges radiating effect by No. five sensors 185, No. six 186 two temperature sensors of sensor.When 185>No. six sensors 186 of No. five sensors, radiating effect has been described.When 185<=No. six sensors 186 of No. five sensors, no radiating effect is described, control system can be opened switch valve 1509 No. nine, closes No. five sensors 185, No. six sensors 186.By No. three sensors 183 of TEMP, judge that low-temperature receiver water is whether to reach the required desirable sink temperature of heat pump 100, this ideal sink temperature is to add the comparatively ideal temperature that electricity price is at that time calculated by the parameter that control system has been collected each equipment, if do not reach this temperature, control system can start cooling tower 600, simultaneously open 1511, ten No. two switch valves 1512 of ride on Bus No. 11 switch valve automatically, close switch valve 1510 valves No. ten.Like this, just reached the purpose of control integrated cost.
The system of winter heating
Winter heating mainly provides the domestic hot-water.Cardinal principle is to utilize water that heat pump 100 adds thermal storage heat water tank 800 with accumulation of heat, delivers to the user after the 3rd coil pipe 808 of domestic water by cold-storage water tank 800 is heated.In the winter time, still use in the cooling medium loop when freeze summer, and two No. ten switch valve 1520, two ride on Bus No. 11 switch valves 1521 are closed, and 20 No. two switch valve 1522 is opened, and forms only user's a simple heating circuit.The heat energy of heat pump 100 all is sent to accumulation of energy water tank 800.The thermal source loop of heat pump 100 by heat pump 100, hot coil 400, solar thermal collector 500, electric heater 700 form.Heat cold water that heat pump 100 comes out and directly get to underground thermostat layer through pump 111, a switch valve 1501, be heated into the water of heat by thermostat layer, entering solar thermal collector 500 then heats once more, when No. five sensors of temperature sensor 185, No. six sensors 186 sense 186<=No. five sensors 185 of No. six sensors, illustrate that solar thermal collector 500 can not provide heat, robot control system(RCS) can be opened switch valve 1509 No. nine, close No. five switch valves 1505, No. six switch valves 1506, the hot water bypass is crossed solar thermal collector 500.Then through 1510, ten No. five switch valve 1515 backheat pumps 100 of No. ten switch valves.The water of backheat pump 100 is by No. three sensor 183 sensings, be lower than when setting value when sensing return water temperature, the automatic opening electric heater 700 of system, 1516, ten No. eight switch valves of ten No. six switch valves 1518 keep cutting out, 1513, ten No. four switch valves 1514 of ten No. three switch valves are opened, ten No. five switch valve 1515 cuts out, and backwater is heated to setting value.To be the performance parameter of gathering electric heater 700, heat pump 100 etc. by control system calculate in conjunction with electricity price at that time setting value, is an often value of change, and the variation of each relevant parameter is all returned and had influence on it, and its calculating purpose is saved cost exactly.
