Temperature=[setting value 2], DC frequency-changeable compressor carry out frequency reducing adjusting；When refrigeration side heat exchanger middle portion temperature=[setting value 6],
Or outdoor heat exchanger middle portion temperature=[setting value 3], DC frequency-changeable compressor stop.
7. the control method of bathroom integrated air conditioner unit in high-efficiency and energy-saving type kitchen according to claim 3, feature exist
In the electronic expansion valve controls of operation heat exchanger in cooling mode, according to the heat exchanger inlet and outlet mistake at a temperature of varying environment
Temperature is adjusted, i.e., when actually detected inlet and outlet degree of superheat > target superheat degree, carries out valve opening adjusting；When actually detected
Degree of superheat < target superheat degree is imported and exported, pass valve regulation is carried out；When the actually detected inlet and outlet degree of superheat=target superheat degree, valve
Aperture is kept；Import and export the degree of superheat=outlet temperature-inlet temperature；
The electronic expansion valve controls for running heat exchanger in a heating mode, are adjusted according to the suction superheat under varying environment
Section carries out valve opening adjusting that is, when actually detected suction superheat > target suction superheat；When actually detected suction superheat
< target suction superheat is spent, pass valve regulation is carried out；When actually detected suction superheat=target suction superheat, valve opening
It keeps；Suction superheat=suction temperature-outdoor heat exchanger coil temperature；
Adjusting is modified to electronic expansion valve opening when excessive discharge temperature simultaneously, i.e., when delivery temperature >=[setting value 7], into
Row valve opening is adjusted, and is control target with delivery temperature < [setting value 7], and limit electric expansion valve minimum according to delivery temperature and open
Degree, i.e., when delivery temperature >=[setting value 8], limiting electric expansion valve minimum aperture is [setting value 10]；As [setting value 9]≤row
Temperature degree < [setting value 8], limitation electric expansion valve minimum aperture are [setting value 11]；When delivery temperature < [setting value 9], limit
Electric expansion valve minimum aperture processed is [setting value 12].
