Formula ew=ewsexp[13.3185×(1-TS/Td)-1.9760×(1-TS/Td)2-0.6445×(1-TS/Td)3-0.1299×
(1-TS/Td)4] calculate acquisition, ewsIt, can value 1013.25hPa for constant.
It, can also (outdoor environment temperature-be current big according to preset table in another embodiment of the application
Atmospheric pressure-outdoor dew-point temperature) obtain air conditioner refrigerating operaton when dew-point temperature.Wherein, preset table is to pass through
Many experiments test obtains.
The temperature in the second throttle part exit can be obtained by the way that the temperature sensor in the second throttle part exit is arranged in
It takes, the temperature of acquisition is denoted as the first temperature.
In one embodiment of the application, before the dew-point temperature of acquisition air conditioner in cooling mode, further includes: ring
Should be in the instruction that control air conditioner is run in cooling mode, and the aperture for controlling the second throttle part is maximum.That is,
When air conditioner is run in a chiller mode, heating throttle part does not work, the second throttle part standard-sized sheet, at this time condensator outlet
Temperature and the first temperature are essentially identical.
S2 is adjusted the aperture of the second throttle part according to the first temperature and dew-point temperature.
According to one embodiment of the application, the aperture of the second throttle part is carried out according to the first temperature and dew-point temperature
It adjusts, comprising: meet first condition between the first temperature of identification and dew-point temperature, wherein first condition is that the first temperature is greater than
Dew-point temperature and the difference of the first temperature and dew-point temperature are greater than the first preset value；The second throttle part is controlled according to preset step-length
Reduce current aperture.Wherein, the first preset value and preset step-length can be demarcated according to the actual situation, for example, first is default
Value can be 1 DEG C.
Specifically, it after air conditioner is run in a chiller mode, and air conditioner runs a period of time, obtains air conditioner and is freezing
The first temperature Tj of dew-point temperature Td and the second throttle part exit under operation heat throttle part at this time and do not work,
The temperature gap between dew-point temperature Td and the first temperature Tj is obtained, and temperature gap is judged, when Td-Tj≤the first is pre-
If be worth (such as 1 DEG C), keep current aperture constant；When the first preset value of Td-Tj > (such as 1 DEG C), illustrate the two temperature difference
It is larger, in order to guarantee refrigeration effect, can reduce the second throttle part aperture (aperture of the second throttle part is smaller, throttling
Effect is better, and temperature decline is bigger, and refrigeration effect is better), the second throttle part of control reduces current aperture with preset step-length,
The aperture that the second throttle part is reduced according to the rate of preset step-length, until being unsatisfactory for first condition.
In one embodiment of the application, control the second throttle part according to preset step-length reduce current aperture it

Temperature and the second preset value can be demarcated according to the actual situation, for example, default delivery temperature can be 100 DEG C, second is default
Value can be 13 DEG C.
That is, before being turned down to the aperture of the second throttle part, can also judge after meeting first condition
Whether second condition or third condition are met.When delivery temperature Tp < presets delivery temperature (such as 100 DEG C), alternatively, outlet temperature
T3 > the first temperature Tj and when the second preset value of T3-Tj > (such as 13 DEG C), the second throttle part of control is reduced according to preset step-length
Current aperture.
In one embodiment of the application, control the second throttle part according to preset step-length reduce current aperture it
Afterwards, further includes: continue that the first temperature, dew-point temperature and outlet temperature and delivery temperature are obtained and identified；Identification first
Do not meet first condition between temperature and dew-point temperature；Or, identification delivery temperature does not meet second condition；Or, identification outlet temperature
Do not meet third condition between degree and the first temperature；The current aperture for controlling the second throttle part is updated to previous aperture.
Specifically, it after the aperture to the second throttle part reduces, also continues obtaining the first temperature Tj, dew-point temperature
The outlet temperature T3 of Td, delivery temperature Tp and condenser, to being judged accordingly.It is default when first appearing Tj-Td≤the first
It is worth (such as 1 DEG C) (the first temperature of explanation is close with dew-point temperature, and dew condensation phenomenon may occur in air-conditioning component), alternatively, T3-Tj
The second preset value of > (such as 13 DEG C) (refrigerating capacity is not able to satisfy user demand), alternatively, first appearing Tp >=default delivery temperature
(such as 100 DEG C) (delivery temperature of compressor will limit the running frequency of compressor when being more than default delivery temperature, influence compressor
Stable operation) when, the aperture for recording the aperture of current second throttle part, and controlling the second throttle part is restored to one and opens
Degree, and the above aperture is run, for example, current aperture is 80, preset step-length 3, then not meeting above three item in judgement
In part when wherein giving condition, the aperture of the second throttle part of control restores a upper aperture 83, and the second throttle part of control
It is 83 operations with aperture.
In one embodiment of the application, control the second throttle part current aperture be updated to previous aperture it
Afterwards, further includes: preset step-length is reduced, the second throttle part of control reduces current open according to the preset step-length after diminution
Degree, and continue that the first temperature, dew-point temperature and outlet temperature and delivery temperature are obtained and identified.
That is, will reduce the rate of aperture reduces, for example, preset step-length is a, step-length after diminution is b, and 2≤b
< a.After controlling the second throttle part with the operation of previous aperture, reduce current aperture with b step-length, for example, previous
Aperture is 83, after reducing b (such as 2), controls the second throttle part and is run with 81 aperture, and continue to the first temperature, dew point temperature
Degree, outlet temperature and delivery temperature are detected, until meeting Tj-Td≤1 DEG C, alternatively, returning when first appearing Tp >=100 DEG C
To the aperture operation of last second throttle part.
In one embodiment of the application, after the dew-point temperature for obtaining air conditioner, further includes: will be when time dew of acquisition
Point temperature is compared with the preceding dew-point temperature once obtained, is identified when time dew-point temperature of acquisition and the preceding dew once obtained
For difference between point temperature within the scope of preset difference value, the dew-point temperature for controlling air conditioner continues to use the preceding dew point once obtained
Temperature；It identifies when the difference between time dew-point temperature and the preceding dew-point temperature once obtained of acquisition is not in preset difference value range
Interior, the dew-point temperature for controlling air conditioner is updated to when time dew-point temperature of acquisition.Wherein, preset difference value range can be according to practical feelings
Condition is demarcated, for example, preset difference value can be 0.5 DEG C.
In other words, when air conditioner is run in a chiller mode, the aperture standard-sized sheet of the second throttle part obtains current dew
Point temperature Td1, Td=f (T4, Ts, P) carry out obtaining a dew-point temperature Td2 every preset time (such as 1 hour), and to phase
Adjacent dew-point temperature twice is compared, if abs (Td2-Td1)≤0.5 DEG C, does not update Td value (the dew point temperature obtained
Degree is Td1), if 0.5 DEG C of > of abs (Td2-Td1), Td value (dew-point temperature obtained is Td2) is updated, and according to update
The aperture of the second throttle part is adjusted in Td value and the first temperature value afterwards.Wherein, the acquisition methods of dew-point temperature exist
