Specific embodiment
The technical scheme of the present invention will be explained in further detail with reference to the accompanying drawings and detailed description.
Embodiment 1
The air conditioner room unit of the present embodiment includes shell, and air inlet and air outlet, setting in shell are provided on shell
There are indoor heat exchanger and blower.Wherein, indoor heat exchanger and blower, room are set gradually between air inlet and air outlet in shell
Interior heat exchanger has indoor coil.Wind deflector is provided at air outlet, for being oriented to the air-flow at air outlet.Air conditioner
When normal operation, compressor operation drives the refrigerant interior flowing of heat exchanger indoors, and blower rotation makes room air from air inlet
Into in shell, it is expelled to interior from air outlet with after indoor heat exchanger progress heat exchange, the steering for defining blower at this time is positive
To rotation.
The present embodiment proposes a kind of air conditioner heat-production start-up control method, in air conditioner heat-production booting, controls blower
It rotates backward, is formed and blow to the air-flow of indoor coil, room air enters in shell from the air outlet of air conditioner, and from air conditioner
Air inlet blowout.Thus, the air outlet of air conditioner enters the wind not outlet air, and air outlet will not blow out the cold wind for making us not feeling like oneself.
Meanwhile the air-flow for blowing to indoor coil can guarantee the condensing pressure of indoor heat exchanger in the reasonable scope, guarantee indoor heat exchange
Device condensing pressure is not excessively high, can solve heating booting when system pressure it is excessive and lead to the problem of pressure protection shutdown.Wherein,
The counter-rotational direction of blower rotates forward contrary with blower.
As shown in Figure 1, the present embodiment proposes a kind of air conditioner heat-production start-up control method, include the following steps:
S1, air conditioner receive booting heating signal, and booting heating signal is transmitted to control module.Wherein, booting system
Thermal signal can be starting-up signal and heating signal, or the memory in heating mode when starting-up signal and last time shut down
Heat signal.
After S2, control module receive booting heating signal, coil temperature sensor detection coil temperature is simultaneously transmitted to control
Module.
After control module receives booting heating signal, also control wind deflector is opened, and compressor start operation, refrigerant is being made
Flowing in cold loop.
S3, control module judge whether coil temperature is higher than second temperature given threshold, if being higher than second temperature sets threshold
When value, S4 is entered step, otherwise, continues the coil temperature sensor detection coil temperature in step S2 and is transmitted to control module
