Abstract
The invention relates to a synergia antifreezing water source heat pump device, and belongs to the technical field of heat exchange. The heat pump device provided by the invention is composed of a heat pump set, a water inlet pipe, a drain pipe and a water pump, wherein a one-way valve is arranged on the water inlet pipe which is arranged between the water pump and the heat pump set, and a high level cistern is arranged above the heat pump set; the high level cistern is provided with an upper water pipe and a lower water pipe, and the other ends of the upper water pipe and lower water pipe are both connected with the water inlet pipe which is arranged between the one-way valve and the heat pump set; and the lower water pipe is provided with an abnormal electromagnetic valve. The heat pump device is characterized in that geothermal water is fully filled into the high level cistern at firstly, and then enters into the heat pump set to carry out heat exchange through the water inlet pipe; when the system is in outage, the abnormal electromagnetic valve is opened, the hot water in the high level cistern flushes into the heat pump set, and the cold water in the heat pump set is discharged. The heat pump device provided by the invention has the advantages of improving the efficiency of a water-source heat pump set, and preventing the water-source heat pump set from being frozen.
Description
Technical field:
The invention belongs to technical field of heat exchange, is a kind of headwaters heat pump.
Background technology:
Water source heat pump technology is saved advantages such as fossil energy and environmental protection in the extensive use already of countries such as America and Europe with it, it adopts source pump, water inlet pipe, drainpipe, water pump and check valve to constitute, water pump is delivered to geothermal water in the source pump by water inlet pipe, carry out heat exchange, obtain heat energy, afterwards, cold water returns underground from drainpipe.In recent years, water source heat pump technology is also very rapid in China's development, but many problems in use also occurred.The northern area of China is the maximum area of heat supply in winter demand, the leaving water temperature of most of regional water source heat pump system ground pumped well is at 10 ℃, reach northern territory, Xinjiang leaving water temperature northeastward and can hang down, at this moment, have only temperature at discharging condensate is arranged on 1-3 ℃ just carries out heat exchange to 6 ℃.This situation has influenced the service efficiency of water resource heat pump greatly, and during system cut-off, remaining cold can freeze damage with the source pump coil pipe, causes the damage of equipment.
Summary of the invention:
The technical problem to be solved in the present invention is to disclose a kind of antifreeze headwaters heat pump of synergy that can use safely under the low situation of inflow temperature.
The scheme of technical solution problem of the present invention is to adopt source pump, water inlet pipe, drainpipe and water pump to constitute the antifreeze headwaters heat pump of synergy, on the water inlet pipe between water pump and the source pump, check valve is housed, elevated tank is equipped with in the top of source pump, upper hose and downcomer are installed on the elevated tank, the other end of upper hose and downcomer all is connected on the water inlet pipe between check valve and the source pump, and the anti-convention magnetic valve is housed on the downcomer.Wherein the anti-convention magnetic valve is to cut out under normal operation, the valve of opening during system cut-off.
When starting working, start water pump, geothermal water is filled elevated tank by water inlet pipe and upper hose earlier, enter source pump by water inlet pipe again and carry out heat exchange, when system cut-off, the anti-convention magnetic valve is opened, owing on the water inlet pipe check valve is arranged, hot water in the elevated tank pours source pump, and the cold water in the source pump is discharged, and prevents that the source pump coil pipe from freezing damage.
Settling the indoor temperature of the pump house of source pump is 15 ℃, and the water yield that the underground heat pumped well can be taken out is 200th
-1, the leaving water temperature of pumped well is 7 ℃.Before this device was not installed, the water of extracting out from pumped well was expelled back in the gully through water source heat pump units circulation coil pipe.When outage suddenly; refrigeration in the source pump evaporator coil is still in the evaporation heat absorption; in order to make the water that remains in the water source heat pump units circulation coil pipe be unlikely to frozen, water source heat pump units is frozen damage, the water conservation temperature that goes out of water source heat pump units is set to 3 ℃.So the heat that source pump was extracted in a hour mostly is Q=200 * 10 most
3* 4200 * (7-3)=3.32 * 10
7J.After this device was installed, under the situation of the normal operation of system, the anti-convention magnetic valve was in closed condition, and the water of extracting out from pumped well enters elevated tank through check valve, and after after a while, the water in the water tank reaches 15 ℃ of room temperatures.When outage suddenly, water in the circulation line stops circulation, the anti-convention magnetic valve is in opening, water in the elevated tank enters water source heat pump units circulation coil pipe, refrigeration in the source pump evaporator coil is still in the evaporation heat absorption, enter water source heat pump units circulation coil pipe this thermal source just in time is provided, make water source heat pump units circulation coil pipe be unlikely to frozen.Because this cover protective device has been arranged, can source pump minimumly go out the water conservation temperature and be set to 1 ℃, under the situation of same traffic, extractible heat mostly was Q=200 * 10 most in one hour
3* 4200 * (7-1)=4.48 * 10
7J compares the water source heat pump system that this device is not installed, and efficient improves more than 50%, and will prevent the strategy that water source heat pump units is frozen damage to be prevented by the active that passive prevention is transformed into, and can avoid water source heat pump units to be frozen damage, guarantees to heat and normally carries out.
Internally piloted valve is equipped with in upper hose porch at elevated tank, closes upper hose automatically after can making the elevated tank topped up with water.
The present invention can improve source pump minimumly goes out the water conservation temperature, and under the situation of same traffic, the heat of extraction increases, and has improved the efficient of water source heat pump units, has avoided water source heat pump units to be frozen damage.

Accompanying drawing is a schematic diagram of the present invention.
The specific embodiment:
The present invention is made of source pump 1, water inlet pipe 2, drainpipe 3 and water pump 4, on the water inlet pipe 2 between water pump 4 and the source pump 1, check valve 5 is housed, elevated tank 6 is equipped with in the top of source pump 1, upper hose 7 and downcomer 8 are installed on the elevated tank 6, the other end of upper hose 7 and downcomer 8 all is connected on the water inlet pipe 2 between check valve 5 and the source pump 1, anti-convention magnetic valve 9 is housed on the downcomer 8, internally piloted valve 10 is housed in upper hose 7 porch of elevated tank 6.
