開冷氣可否使室內溫度增加

戈架唔係叫冷氣機，係叫空氣調節機，Air-Conditioner，或叫空氣調節系統被稱為HVAC ，佢内邊有多一個雙向伐，four way valve，夏天時吹冷氣，冬天時吹熱氣既。

Key Specifications/Special Features:


It diverts the direction of the refrigerant flow under the electromagnetism of the pilot valve
to supply either heating in winter or cooling in summer to the conditioned place
Capacity: 9kW
Power: 3/4 to 2.0hp
Internal leakage: less than 2,000ml/min
Maximum operation pressure differential: 2.25MPa
Refrigerants: R22, R407c, R134a, R410a
Connection at high-pressure side: 9.65mm
Connection at low-pressure side: 12.8mm
Minimum operation pressure differential: 0.34Mpa

如果如你所說, 開冷氣(唔係開冷氣機)係唔可能使室內溫度增加.
市面有 d 冷氣機似的, 叫 heat pump, 平時係冷氣機, reverse cycle 時放暖氣的.

不可以,除非開冷氣

冷氣機裡有調節溫度的掣鍵
如果你把溫度調窗至高於室內的溫度
便可以使室內溫度增加
