Description of drawings
With reference to the accompanying drawings the present invention is described in more details, wherein
Fig. 1 shows the synoptic diagram of the air conditioner that warning device of the present invention is installed;
Fig. 2 is the workflow diagram of warning device of the present invention.
Embodiment
Schematically shown the air conditioner that warning device of the present invention is installed as Fig. 1, described air conditioner mainly is made of indoor set 1, off-premises station 2 and refrigerant circulation line.Refrigerant circulation line comprises pressure duct 5 and low pressure line 6.Be example with the working condition of air-conditioning under refrigeration mode below, the principle of work of air conditioner refrigerating done simple introduction:
At first, in off-premises station 2, with the cold-producing medium of gaseous state (for example by compressor, freon) gas of boil down to High Temperature High Pressure, delivering to the heat interchanger (condenser) of off-premises station then, become the liquid refrigerant of normal temperature high voltage after the condensation liquefaction heat release, is hot blast so off-premises station produces by boasting.
Subsequently, the liquid refrigerant of normal temperature high voltage enters heat interchanger (evaporator) the indoor set 1 from high-voltage tube, because arriving the evaporator rear space, cold-producing medium increases suddenly, pressure reduces, and liquid cold-producing medium will be vaporized, and becomes the gas of low temperature, thereby absorb a large amount of heats, evaporator will turn cold, and the fan of indoor set is blown over indoor air from evaporator, is exactly cold wind so indoor set produces by boasting; Airborne water vapour will become water droplet after running into cold evaporator, flows out along water pipe.
After this, the cold-producing medium of gaseous state is got back to compressor and is continued to be compressed, and so circulation makes indoor temperature constantly reduce.
The above is the process of refrigerastion of air-conditioning, when using air-conditioning to heat, use the four-way valve that is installed between pressure duct 5 and the low pressure line 6 that the transposing of two pipelines is come, thereby outdoor when heating what blow is cold wind, what indoor set blew is hot blast, and this process is opposite with refrigeration.
In the course of work of air-conditioning system, have higher pressure in the pressure duct 5, have relatively low pressure in the low pressure line 6.When the air-conditioning system shutdown, when promptly compressor was not worked, the pressure equilibrium in the height pressure pipe was equalized pressure.
Warning device of the present invention comprises pressure sensing cell and alarm unit.Described pressure sensing cell is realized by the pressure switch 3 that is installed on the cold-producing medium pressure duct, described alarm unit for example adopts the computer plate 4 that links to each other with pressure switch, have pressure signal on this computer plate 4 and accept port L1, L2 and warning device, warning device can comprise local warning device (as hummer, LED light etc.) and remote alarming device (as long-range output interface O1, O2 etc.).
Need to prove, owing to when air-conditioning system is worked, be high-pressure in the pressure duct, and when air-conditioning system is shut down, be equalized pressure in the pressure duct 5 herein.Therefore, need make the predetermined pressure of pressure switch be lower than the equalized pressure of pipeline, preferably in the scope of 0.12-0.18MP.Like this; in running order or the stopped status of compressor of air-conditioning system no matter; in case off-premises station is stolen, its refrigerant circulation line is destroyed and refrigerant external leakage and high-voltage tube internal pressure is descended, and pressure switch 3 can in time sense the pressure variation and send induced signal.And, when the phenomenon because of air-conditioning fault or the aging freezing medium leakage that causes takes place, people generally can not discover, just can know and must detect it by the professional, adopt this design, by setting the predetermined pressure of suitable pressure switch 3, also can reach the whether very few purpose of real-time monitoring refrigerant amount.
In addition, in the local warning device, pilot lamp preferably uses LED green light and LED red light, by the control signal of computer plate 4 output to LED light bright, go out and control.During normal condition, LED green light Chang Liang, and abnormal conditions are when occurring, the normal bright or flicker of LED red light.Certainly, as possibility, also can only use a LED light, under normal circumstances for often going out, and be normal bright under abnormal conditions or flicker.Remote alarming device adopts remote signal output interface O1, O2, and for example the RS485/232 interface under normal circumstances to remote supervisory and control(ling) equipment output " normally " signal, and is exported " unusually " signal under abnormal conditions.In addition, can also on computer plate 4, reserve some interface A, B, C, D,, for example give the alarm with short message mode in the diagram and remind user's note dispensing device so that in follow-up use, append other forms of warning device according to user's needs.
Below in conjunction with Fig. 2 the course of work of warning device of the present invention is described.
After connecting the power supply of warning device, device is started working.
When air-conditioning system is in normal condition, have higher pressure in the pressure duct, pressure switch 3 is closed under pressure.Local warning device and remote alarming device on the computer plate 4 are normality, that is, the LED green light Chang Liang of local warning device, hummer is sounding not, and remote signal output interface O1, the O2 of remote alarming device is to remote supervisory and control(ling) equipment output " normally " signal.
When air-conditioning system is in abnormality, promptly owing to stolen when the cold-producing medium pressure duct is damaged, the refrigerant external leakage in the pipeline, pressure descends rapidly, in case line pressure is lower than preset pressure, then pressure switch 3 disconnects under gas pressure.The pressure signal of computer plate 4 is accepted port L1, L2 and is received electric signal from pressure switch, the output control signal, local warning device and remote alarming device are reported to the police, promptly, the LED blinking red lamp of local warning device, the hummer sounding, remote signal output interface O1, the O2 of remote alarming device is to remote supervisory and control(ling) equipment output " unusually " signal.Certainly, warning device can be selected wherein one or more as required arbitrarily.
Like this, when air-conditioner outdoor unit 2 was stolen, warning device of the present invention can provide alarm for local and remote user, thereby makes the user find larceny timely and accurately, avoids property loss.
