The blower 2 answered is closed, and the valve 8 and valve 12 at fourth ventricle external heat exchanger both ends are closed, and blower 6 corresponding to fourth ventricle external heat exchanger closes
It closes, the valve 7 and valve 11 at third outdoor heat exchanger both ends are closed, and the corresponding blower 5 of third outdoor heat exchanger is closed, and are opened other and are changed
Hot device and blower, and control other blowers and run at high speed, compressor is controlled with 1/2 operation of highest frequency.
When temperature deviation is less than or equal to f, outdoor environment temperature is detected；When outdoor environment temperature is less than g, control pressure
Contracting machine running frequency is the 1/2 of highest frequency；An indoor heat exchanger job is controlled, and controls the corresponding room of the indoor heat exchanger
The operating of inner blower middling speed；It controls two outdoor heat exchangers to open, and controls the corresponding outdoor fan middling speed of these outdoor heat exchangers
Operating.
When temperature deviation is less than or equal to f, illustrate that current indoor environment temperature has reached within target temperature range,
Illustrate that the heat exchange amount of indoor heat exchanger has met indoor heating demand, needs to consider the ratio of outdoor environment temperature and preset value
Compared with to enable air-conditioning under upper state to compressor, indoor heat exchanger, indoor fan and outdoor heat exchanger and outdoor
Blower is adjusted, and enables the output power of compressor and the heat exchange amount of outdoor heat exchanger and the heat exchange amount phase of indoor heat exchanger
Match.When temperature deviation is less than or equal to f, illustrate that current indoor environment temperature has reached within target temperature range, therefore
Only needing air-conditioning to export lower power just can satisfy current heating needs, therefore control an indoor heat exchanger job,
And the corresponding indoor fan middling speed operating of the indoor heat exchanger is controlled, in order to guarantee the heat exchange of indoor heat exchanger and outdoor heat exchanger
Balance is kept between amount, is controlled two outdoor heat exchangers and is opened, and controls the corresponding outdoor fan middling speed of these outdoor heat exchangers
Operating illustrates that outdoor environment temperature is lower, outdoor compressor needs to export one higher when being less than g due to outdoor environment temperature
Frequency balance is kept guaranteeing it between indoor heating capacity, therefore control compressor with 1/2 operation of highest frequency, enable
Indoor heating needs and the output power of compressor, the heat exchange amount of outdoor heat exchanger, the heat exchange amount of indoor heat exchanger phase always
Mutually matching, while indoor environment temperature can be finely adjusted, enable indoor environment accurately to reach set temperature.
