The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, concentrates on studies and a kind of humiture induction type intelligent frequency-conversion ventilation unit is provided through the inventor.
The operation principle of described humiture induction type intelligent frequency-conversion ventilation unit:
When indoor temperature requires to be t
0℃, when humidity requirement is n%, these two parameters input native systems as basic reference quantity, and are calculated an initial balance air quantity V according to indoor thermal source state
0
When the humiture of indoor and outdoor changes, by the Temperature Humidity Sensor that is distributed in indoor and outdoor the data that collect are sent to intelligence control system, intelligence control system is according to these data process calculation process, the control frequency converter increases or reduces power stage, thereby the air quantity of control blower fan is to satisfy the constant of indoor temperature and humidity.
Suppose that the some time outdoor temperature is t
1, indoor temperature is t
2, work as t
1＜t
0＜t
2, namely to satisfy by VMC indoor condition of lowering the temperature, this moment, VMC started, the putting in blast of turnover blower fan.Induction type frequency converter in the intelligence control system will be according to following formula adjustment air-supply air quantity: △ V=V
0(t
2-t
0)/(t
0-t
1); When the temperature rises, t
1T
0The time, can't be to indoor the cooling time, automatically start air-conditioning temperature-reducing by VMC this moment, and VMC is closed.
The adjustment of humidity is consistent with above-mentioned principle.Suppose that the damp condition that needs to satisfy is n, the some time outside humidity is n
1, indoor humidity is n
2, work as n
1＜n＜n
2, namely to satisfy by VMC indoor condition of carrying out clearing damp, this moment, VMC started, the putting in blast of turnover blower fan.Frequency converter in the intelligence control system will be according to following formula adjustment air-supply air quantity: △ V=V
0(n
2-n)/(n-n
1); When outside humidity rises n
1During n, can't to indoor when carrying out clearing damp, automatically start air-conditioning clearing damp by VMC this moment, VMC is closed; When outside humidity excessively low, n
1＜n
2During＜n, automatically start humidifier, VMC is closed.
In concrete the use, possible some place is higher than humidity to temperature control requirement, and control requires to be higher than temperature to humidity in other places, can design temperature control preferential or humidity control preferentially.
