Abstract
The invention discloses a fan control method for judging a condition of heating to a set temperature by an air conditioner. The fan control method comprises the following specific steps: a, under a heating mode, detecting a room temperature sensor, stopping a compressor after a set temperature is reached, and regulating an indoor fan to operate at a low air gear; b, after the temperature value measured by the indoor sensor is reduced to a re-starting temperature of the compressor, judging whether the stop time of the compressor conforms to the shutdown protection time, and if the stop time conforms to the shutdown protection time, entering the step c, otherwise, entering the step d; c, directly re-starting the compressor, re-operating the heating mode and regulating the indoor fan to operate at a normal air gear; and d, turning off the indoor fan until the stop time of the compressor conforms to the shutdown protection time, re-starting the compressor and re-operating the indoor fan at the normal air gear after lagging by one hot air protection time period. The fan control method not only can ensure that the compressor can timely re-start, but also can prevent cold outlet air of the indoor fan.
Description
Technical field
The present invention relates to the control method of air-conditioner; be specifically a kind of judge air-conditioning heating arrive temperature after blower control method, in particular, be when air conditioner heat-production runs; after indoor temperature is heated to design temperature, compressor shutdown, to the control method of indoor fan.
Background technology
The air-conditioner of prior art, in a heating mode, can set the shutdown temperature of compressor and restart temperature, and shutdown temperature is generally that the desired value of indoor temperature of setting adds 1 DEG C, and restarting temperature is generally that the desired value of the indoor temperature of setting subtracts 1 DEG C.Temperature sensor for measuring indoor temperature is arranged on the return air inlet of indoor apparatus of air conditioner.After the temperature recorded when temperature sensor is more than or equal to the shutdown temperature of compressor, compressor is shut down to temperature.Now, indoor fan can continue short-time duty a period of time, until after the coil temperature of indoor heat exchanger is greater than the setting value of fan operation time lower than design temperature or indoor fan running time, after dissipating by the heat of the coil pipe internal reservoir in indoor heat exchanger, just indoor fan is shut down; Then continue to measure room temperature, after temperature is restarted in the temperature arrival of the time and temperature sensor detection that meet compressor shutdown protection, restart compressor heating operation, and continue opening chamber's inner blower after the time of delayed hot blast protection.
There is following drawback in above-mentioned blower control method, namely compressor to be shut down and after indoor fan also stops to temperature, because the installation site of indoor set in room is higher, and hot-air floats, cause the return air inlet position heat accumulation of installation room temperature sensor, and after blowing-out machine also cannot with whole room heat convection, the indoor temperature causing temperature sensor to record is often high than indoor actual temperature, so often there is the condition that room actual temperature has met reset itself and again heats, but compressor can not normally start, make whole room temperature continuous decrease, people is allowed to feel cold uncomfortable.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and can ensure that compression function again starts in time and can avoid the blower control method of judgement air-conditioning heating after temperature of indoor fan air-out cold.
Technical solution of the present invention is, provide a kind of judge air-conditioning heating arrive temperature after blower control method, its concrete steps are as follows:
A, in a heating mode sensing chamber's temperature sensor, stop compressor to temperature, and indoor fan is adjusted to the operation of low wind shelves;
B, when the temperature value that interior sensor records drop to compressor restart temperature after, judge whether the compressor shutdown time meets the time of stoppage protection, if so, then enter step c, if not, then enter steps d;
C, directly reset itself, rerun heating mode, and indoor fan is adjusted to the operation of normal wind shelves;
D, closed by indoor fan, until the compressor shutdown time meets the stoppage protection time, then reset itself, and after the time of delayed hot blast protection, normal wind shelves run indoor fan again.
This controlling party ratio juris is: after compressor is shut down to temperature, indoor fan is switched to low wind shelves continuous service from normal wind shelves, to maintain the heat convection of top and the bottom, room, guarantee that the whole room temperature comprising indoor set return air inlet is balanced, the temperature difference between decontamination chamber temperature sensor measured value and room actual temperature, make once after in room, temperature is restarted in actual temperature arrival, compression function normally starts fast, again heats; And in compressor shutdown process, blower fan all the time low windscreen runs, like this, wind speed and air quantity little, people can not be allowed to feel cold; And indoor temperature meet restart temperature after; if the compressor shutdown time has exceeded the stoppage protection time; then directly normally blow in machine; just in case the compressor shutdown time is shorter; also be less than the time of stoppage protection; then closed completely by indoor fan, avoiding continues to blow a cold wind over makes room temperature decline further.
Adopt above method, the present invention judges that air-conditioning heating arrives the blower control method after temperature compared with prior art, has the following advantages:
1, after heating temperature shutdown, the low wind shelves of indoor fan run, and avoid wind speed excessive, cause room temperature to decline too fast, avoid high wind directly to brush human body simultaneously and produce cold discomfort; 2, indoor fan continuous service, ensures lasting heat exchange in room, avoid due to installation site reason cause temperature sensor and room actual temperature difference excessive and cause that compressor can not be restarted in time, air-conditioning can not recover the situation that heats in time; 3, when indoor temperature meet compressor restart condition but the compressor shutdown time shorter do not meet stoppage protection time, close chamber's inner blower, avoids room temperature to decline further; 4, after compressor is shut down to temperature; because the low wind shelves of blower fan run; room temperature can not too fastly be declined; indoor temperature is made to arrive the time of restarting temperature longer; namely when indoor temperature arrives and restarts temperature, the time of compressor shutdown has often exceeded the time of stoppage protection, is beneficial to starting in time fast of compressor; also ensure that in room, temperature fluctuation is little, improves the comfortableness of user.
Detailed description of the invention
The present invention judge air-conditioning heating arrive temperature after blower control method, its concrete steps are as follows.
A, in a heating mode sensing chamber's temperature sensor, stop compressor to temperature, and indoor fan is adjusted to the operation of low wind shelves; Namely when temperature temperature sensor recorded is more than or equal to shutdown temperature, compressor shutdown.Shutdown temperature is generally that the desired value of the indoor temperature of setting adds 1 DEG C, and the indoor temperature as setting is 30 DEG C, then shutdown temperature is 31 DEG C.Blower fan is generally provided with several gears such as low wind shelves, Gao Fengdang, apoplexy shelves.
B, when the temperature value that interior sensor records drop to compressor restart temperature after, judge whether the compressor shutdown time meets the time of stoppage protection, if so, then enter step c, if not, then enter steps d; The described stoppage protection time refers to, need rest a period of time again to start shooting after compressor shutdown, this is avoided compressor opening and closing too frequently to cause damage, and what time of general stoppage protection established is 3 minutes; Described to restart temperature be generally that the desired value of the indoor temperature of setting subtracts 1 DEG C, and the indoor temperature as setting is 30 DEG C, then restarting temperature is 29 DEG C.
C, directly reset itself, rerun heating mode, and indoor fan is adjusted to the operation of normal wind shelves.
D, closed by indoor fan, until the compressor shutdown time meets the stoppage protection time, the time as compressor shutdown reaches 3 minutes, then reset itself, and after the time of delayed hot blast protection, normal wind shelves run indoor fan again.Described hot blast guard time refers to, HTHP refrigerant again by compressor operating to the time in the coil pipe of indoor heat exchanger, be generally about 15 seconds, after 15 seconds, indoor fan blowout be exactly hot blast.
