(73) then, temperature inductor real-time detection air outlet temperature is transferred to receiving module by temperature transmitter；
(74) then, the temperature that receiving module will test is transmitted to central processing unit；
(75) central processing unit carries out the work of processing operation to the temperature that temperature inductor detects, after central processing unit operation
When temperature difference is less than or equal to predetermined value, operation result can be sent to transmission module by signal by central processing unit；
(76) result received is sent to controller by transmission module；
(77) at this point, controller is judged, heated up or cooled down, thus determine driving device be carry out main story or
Reversion；If heated up, (78) are thened follow the steps, if cooled down, then follow the steps (79)；
(78) servo motor inverts, and baffle (11) retreats, and throttle orifice (3) area blocked on choke block (2) reduces, and increases refrigeration
Agent circular flow, realization significantly cool down；
(79) servo motor main story, baffle (11) advance, and throttle orifice (3) area blocked on choke block (2) increases, and reduce refrigeration
Agent circular flow reduces cooling extent to realize temperature rise effect.
8. the control method of the throttling set of air-conditioning system according to claim 7, it is characterised in that: the step
(78) in, servo motor (6) reversion, servo motor (6) drives screw rod (8) rotation, and screw rod (8) drives transmission nut (9) along silk
Bar (8) moves backward, and link block (10) is driven to move backward, drives baffle (11) to slide backward, baffle (11) blocks choke block
(2) throttle orifice (3) area on reduces, and the flow that refrigerant passes through throttle orifice increases, and refrigerant enters the stream of evaporator (15)
Amount increases, and realization significantly cools down.
9. the control method of the throttling set of air-conditioning system according to claim 7, it is characterised in that: the step
(79) in, servo motor (6) is rotated forward, and servo motor (6) drives screw rod (8) rotation, and screw rod (8) drives transmission nut (9) along silk
Bar (8) travels forward, and link block (10) is driven to travel forward, and drives baffle (11) forward slip, and baffle (11) blocks choke block
(2) throttle orifice (3) area on increases, and the flow that refrigerant passes through throttle orifice is reduced, and refrigerant enters the stream of evaporator (15)
Amount is reduced, and reduces cooling extent to realize heating.
10. the control method of the throttling set of air-conditioning system according to claim 7, it is characterised in that: refrigerant passes through
Collet (1) enters evaporator (15) by the further filtering of filter (18), and liquid refrigerant transports evaporator (15)
After interior, space increases pressure reduction, liquid refrigerant vaporization suddenly, and gaseous refrigerant can absorb a large amount of heat around, into
And cooling effect is played, then by compressor, second compression is recycled with this refrigerant again.
