Abstract
The utility model relates to a clock-control differential pressure type auto frost-thawing air-conditioner, which belongs to a cooling or warming combination device. The utility model comprises a compressor, an electromagnetic directional valve, indoor and outdoor heat exchangers, capillary pipes, a centrifugal blower, an axial blower, a blower motor and an electric control system. In addition, to simple structure and safety, the utility model can control the start-stop time of the air-conditioner and accurately thaw the frost according to the thickness of frost.
Description
The utility model is the differential automatic defrosting air-conditioner of a kind of clock.The combined unit that belongs to refrigeration or heat.
Along with the raising of industrial expansion and people's living standard, air-conditioner has obtained using widely.Control section in existing general air-conditioner is fairly simple, does not have automatic control function, makes troubles to the user.To heat pump air conditioner, defrosting Thickness Control when heat winter, not can solve always yet, now, generally be to control by temperature and time, and this control method is difficult to accomplish that the thickness of frosting layer carries out automatic defrosting according to actual needs, therefore, is difficult to guarantee the normal operation of air-conditioner when heat winter.
In order to solve the problem of above-mentioned existence, the purpose of this utility model provides a kind of energy regularly, and the thickness that can accurately control the frosting layer carries out automatic defrosting, the differential automatic defrosting air-conditioner of simple in structure, safe and reliable clock.
The utility model is the differential automatic defrosting air-conditioner of a kind of clock (being designated hereinafter simply as the clock air-conditioner), by compressor, electromagnetic switch cut down, outdoor heat exchanger, indoor heat exchanger, capillary, centrifugal fan, axial fan, blower motor, electric-control system is formed.Electric-control system comprises clock device and differential automatic defrosting device.
The clock device is by two integrated circuits, liquid crystal numberal tube, and trigger, amplifying circuit and change-over switch are formed.Liquid crystal numberal tube links to each other with two integrated circuits by change-over switch, and trigger links to each other with two integrated circuits, amplifying circuits respectively, and amplifying circuit leads to relay.Electromagnetic switch cuts down and is contained on the compressor outlet pipeline, plays the effect that heats or freeze.After the chip of timer sends signal, make trigger action, circuit is through amplifying, and the actuating of relay in the control major loop makes the clock air-conditioner open (or closing).
Differential automatic defrosting device, by pressure-sensitive diaphragm, microswitch, relay and electric heater are formed.Pressure-sensitive diaphragm, microswitch and electric heater are contained on the outdoor heat exchanger.Relay is contained in the circuit.When heat pump when heat winter, the easy frosting of outdoor heat exchanger.Along with the increase of frosting, air duct is blocked, heat transfer deterioration, in addition entirely ineffective.Because the increase of frost layer, the pressure reduction of the front and back air of outdoor heat exchanger also increases, when the outdoor heat exchanger inside pressure increases, pressure-sensitive diaphragm moves, when pressure reduction reaches certain value under differential pressure action laterally, pressure-sensitive diaphragm makes the microswitch action, make the actuating of relay that is connected in the major loop, at this moment, electromagnetic switch cuts down outage, the blower motor stall, electric heater energising is meanwhile carried out heating work to the frost layer, impels the frost layer to melt rapidly.Pressure reduction also reduces rapidly, and pressure-sensitive diaphragm resets, and microswitch disconnects, and then air-conditioner enters the previous state that normally heats.
This clock air-conditioner can also carry out manual operations.
This clock air-conditioner has following advantage compared with the prior art: can control the time and the temperature of air-conditioner automatically, differential automatic defrosting device can accurately carry out automatic defrosting according to frost thickness, and is simple in structure, safe and reliable etc.
The characteristics of this clock air-conditioner can also obtain further instruction from the following drawings and embodiment.
The schematic diagram of Fig. 1, the differential automatic defrosting air-conditioner of clock;
The clock device schematic diagram of Fig. 2, the differential automatic defrosting air-conditioner of clock.
The figure face code:
The 1--indoor heat exchanger, the 2--compressor, the 3--electromagnetic switch cuts down, the 4--capillary, 5--outdoor heat exchanger, the differential automatic defrosting device of 6--, the 7--axial fan, 8--blower motor, 9--centrifugal fan, the 10--electric-control system, 11--liquid crystal numberal tube, 12--integrated circuit, the 13--trigger, the 14--amplifying circuit, A--heats route, the B--route that freezes, the K--change-over switch.
Below in conjunction with accompanying drawing, the differential automatic defrosting air-conditioner of clock of the present utility model is described in detail.
This clock air-conditioner, by indoor heat exchanger 1, compressor 2, electromagnetic switch cuts down 3, capillary 4, outdoor heat exchanger 5, differential automatic defrosting device 6, axial fan 7, blower motor 8, centrifugal fan 9, electric-control system 10, liquid crystal numberal tube 11, integrated circuit 12, trigger 13, amplifying circuit 14, form.
After selecting to heat work, regulation opens and closes the time of air conditioner, when the opening time that arrives regulation, the clock device provides a signal, make relay work, at this moment, electromagnetic switch cuts down 3 energisings, and air motor 8 is rotated, and drives centrifugal fan 9, axial fan 7 and compressor 2 work, go into indoor heat exchanger 1 and heat release from the high-temperature high-pressure refrigerant vapor stream that compressor 2 is discharged, be condensed into highly pressurised liquid, the throttling step-down through capillary 4 flows into outdoor heat exchanger 5 then, and heat absorption flashes to gas, and sucked by compressor 2, finish a circulation.When heating, frosting can take place in outdoor heat exchanger 5, and along with the frost layer increases, the front and back pressure reduction of outdoor heat exchanger 5 increases, make the pressure-sensitive diaphragm of differential automatic defrosting device 6, to the base pressure side shifting, when pressure reduction reaches certain degree, pressure-sensitive diaphragm promotes microswitch and makes its energising, and make auxiliary reclay work, when relay was worked, then electromagnetic switch cut down 3 commutation and centrifugal fans 9, axial fan 7 stalls, and the connection electric heater.This moment, the frost layer was melted rapidly, and the front and back pressure reduction of outdoor heat exchanger 5 reduces, and pressure-sensitive diaphragm resets, the microswitch outage, and the clock air-conditioner recovers the state that normally heats.When clock air-conditioner operation arrival official hour, the clock device provides a signal, makes relay work, at this moment, blower motor 8 stalls, thus centrifugal fan 9, axial fan 7 and compressor 2 are all quit work.
The model machine of this clock air-conditioner, in through repeatedly test and the use of long period, satisfactory when having reached control accurately, and thickness that can accurately root root knot frost layer carry out the predetermined purpose of automatic defrosting.
