Detailed description of the invention
A kind of air-conditioner water system method of controlling exhaust gas and device, by the pump operation on independence control air conditioner system indoor units water system major loop, realize the air of automatically discharging in above-mentioned water system, avoid conventional exhaust need to dismantle water pump wiring, by force to water pump control loaded down with trivial details, also there is not potential safety hazard.And, realizing on self-bleeding basis, also the water flow switch on water system major loop is monitored, avoid water flow switch malfunctioning time, cause indoor units water system cisco unity malfunction, the situation causing other loads of air-conditioning system impaired further occurs, and is also beneficial to and overhauls air-conditioning system.A kind of air-conditioning system, on the basis of conventional refrigeration pattern and heating mode isotype, add automatic vent pattern, user realizes a key exhaust by controller or control panel, simple, convenient, avoids artificially dismantling the potential safety hazard that water pump wiring brings.Above-mentioned self-bleeding setting, air-conditioning system is run under stable hydraulic pressure, ensure that the abundance of the inner water yield of air-conditioning system, air can not be there is, reduce the probability that heat exchanger is impaired, also reduce the probability because air-conditioning system water system discharge deficiency causes indoor units often out of service.
Below in conjunction with drawings and Examples, a kind of air-conditioner water system method of controlling exhaust gas of the present invention, a kind of air-conditioner water system exhaust control device and a kind of air-conditioning system are elaborated further.
Shown in Fig. 1, it is the air-conditioner water system method of controlling exhaust gas flow chart of one embodiment of the invention.
With reference to figure 1, a kind of air-conditioner water system method of controlling exhaust gas, be exhausted for controlling air-conditioning system indoor units water system, described water system comprises heat exchanger, water pump and water flow switch, described heat exchanger, water pump and water flow switch are communicated with in turn by pipeline and form water circulation major loop, described pipeline arranges automatic exhaust steam valve, and above-mentioned air-conditioner water system method of controlling exhaust gas specifically comprises the steps:
S120: open water pump.
Form different according to air-conditioning system indoor units, water-flow circuit arranges difference, when above-mentioned water-flow circuit is provided with other switching devices, such as, when triple valve, two-port valve or other switching devices, multiple water-flow circuit can be formed.First can control above-mentioned switching device to open or close or conducting extremely a certain state, obtain one of them water-flow circuit, then open above-mentioned water pump.After completing a bleeding, be transformed into another water-flow circuit and proceed exhaust, until all complete bleeding to all water-flow circuits.In the present embodiment, only operation is exhausted to water circulation major loop.
After completing the arranging of above-mentioned switching device, time delay certain hour opens water pump.Concrete, time delay can open water pump after 15 seconds, ensure that water circulation system can conducting.In other examples, also water pump can be opened again after other scheduled times of time delay.
S140: after described starting mode of pump first scheduled time, detects the state of described water flow switch in continuous second scheduled time.
Concrete, above-mentioned first scheduled time is 10-20 second, and above-mentioned second scheduled time is 25-35 second.In another embodiment, above-mentioned first scheduled time is 15 seconds, and above-mentioned second scheduled time is 30 seconds.
By detecting the state of water flow switch, detecting water flow switch and whether to damage or malfunctioning.When above-mentioned water system runs, when discharge is too low, if water flow switch is malfunctioning, when indoor units is run for a long time under low discharge, especially when refrigerating operaton, be easy to occur to temperature spot, indoor units can start and stop frequently, cause heat exchanger to be damaged by frost.Said temperature point, refers to the leaving water temperature point of user's setting.Concrete, said temperature point is 7 DEG C.
Whether to damage or malfunctioning by detecting water flow switch, the generation of the problems referred to above can be avoided, be also beneficial to air-conditioning system and overhaul.
S160: if described state is off, then close described water pump.
If the state of water flow switch disconnects, represent water flow switch malfunctioning or damage.By switching off the pump, stopping bleeding, stopping the loaded work of air-conditioning system, report to the police and pass through display displaying system fault or display water flow switch fault.
S180: if described state is closed, then continue to run described water pump, the air in described water circulation major loop discharges described water system by described automatic exhaust steam valve.
If it is closed for detecting the state obtaining water flow switch, represent that water flow switch is working properly, water pump continues to run, and air-conditioning system all loads except water pump are all failure to actuate.By the dynamic action of water pump, the water in above-mentioned water-flow circuit circulates, the air in water system along with water circulation to above-mentioned automatic exhaust steam valve time automatically discharge.
Above-mentioned air-conditioner water system method of controlling exhaust gas, by the pump operation on independence control air conditioner system indoor units water system major loop, realize the air of automatically discharging in above-mentioned water system, avoid conventional exhaust need to dismantle water pump wiring, by force to water pump control loaded down with trivial details, also there is not potential safety hazard.And, realizing on self-bleeding basis, also the water flow switch on water system major loop is monitored, avoid water flow switch malfunctioning time, cause indoor units water system cisco unity malfunction, the situation causing other loads of air-conditioning system impaired further occurs, and is also beneficial to and overhauls air-conditioning system.
Shown in Fig. 2, it is the air-conditioner water system exhaust control device schematic diagram of one embodiment of the invention.
With reference to figure 2, a kind of air-conditioner water system exhaust control device 100, is exhausted for being controlled air-conditioning system indoor units water system 200 by above-mentioned air-conditioner water system method of controlling exhaust gas.Above-mentioned water system 200 comprises heat exchanger 220, water pump 240 and water flow switch 260, and above-mentioned heat exchanger 220, water pump 240 are communicated with water flow switch 260 in turn by pipeline (figure does not mark) and are formed water circulation major loop, above-mentioned pipeline are arranged automatic exhaust steam valve 280.Concrete, above-mentioned automatic exhaust steam valve 280 is located at pipeline and is positioned at indoor units top.
