Wherein, assembled air-conditioner i.e. group is empty, refers generally to unitary air handling unit, is sometimes also air-treatment unit, all Refer to commercial big tail end air conditioner unit.

As a result, by obtaining the wet-bulb temperature of assembled air-conditioner environment in cooling mode, can be provided for condensation judgement Accurate and reliable foundation, and processing mode is easy.

In an optional example, an embodiment of wet-bulb temperature can be obtained in method of the invention as shown in connection with fig. 2 Flow diagram, further illustrate one of the wet-bulb temperature tool that the assembled air-conditioner local environment is obtained in step S110 Body process.

Step S210 obtains the dry-bulb temperature of the assembled air-conditioner local environment detected by Temperature Humidity Sensor.

Such as: Temperature Humidity Sensor sense detects dry-bulb temperature TG.

The ring is calculated according to the dry-bulb temperature and the design factor being adapted to the environment in step S220 The wet-bulb temperature in border.

Specifically, it in step S220, can be adapted to according to the dry-bulb temperature and with the environment first default Design factor and the second default design factor, are calculated the wet-bulb temperature of the environment.That is: the described wet-bulb temperature=described The one default design factor × dry-bulb temperature+second default design factor.

Such as: wet-bulb temperature TS=A × TG+B is calculated, wherein A, B are constant.

Alternatively it is also possible to directly be calculated using approximate formula.Such as: it can use formula (dry-bulb temperature+wet bulb temperature Degree) * 0.7+40.6=humidity calculated.Certainly, other simple formulas can also be with.

As a result, by the dry-bulb temperature of detection environment, and then environment is calculated according to the design factor being adapted to environment Wet-bulb temperature, detection mode is easy, calculates high reliablity, and at low cost.

In an optional example, the another of the wet-bulb temperature of the assembled air-conditioner local environment is obtained in step S110 A detailed process may include: the wet bulb for obtaining the assembled air-conditioner local environment detected by wet bulb temperature sensor Temperature.

It detects to obtain the wet-bulb temperature of environment by wet bulb temperature sensor as a result, detection mode is easy, testing result essence Parasexuality is good.

At step S120, determine whether the wet-bulb temperature is less than or equal to preset dew-point temperature.

Such as: in the case where under the auxiliary heat of no electricity and dehumidification equipment, by a kind of novel device or equipment come automatic Condensation situation is detected whether.

Such as: the wet-bulb temperature under real-time detection refrigeration mode, and be compared with local dew-point temperature, it can control in time Condensation problem.

As a result, by the way that wet-bulb temperature to be compared with dew-point temperature, judged with the condensation of realization group sky, judgment mode letter Just, judging result accuracy is good.

At step S130, when the wet-bulb temperature is less than or equal to the dew-point temperature, it is empty to adjust the combined type The air-valve of tune, and/or the aperture of water valve, so that the current wet-bulb temperature of the environment is greater than the dew point temperature after the adjusting Degree realizes that the anti-condensation control to the assembled air-conditioner controls.
