Roof Top Air Conditioner

Fanmak roof-top air conditioners are manufactured as standard in 8 different models, with a capacity range of 50 000 btu / h to 400,000 Btu / h. R / 410 A and R / 407 C gas are used which do not harm the environment. Heating is done with heat- pump system. In very cold areas the electric heater is reinforced. Hot-water battery is used in devices without heat-pump. Since it is one piece, it provides ease of installation. Insulation material with 20 mm rubber is used in the inner parts. G4 quality panel filter is used as standard in the evaporator air inlet. The fans used are selected as belt pulleys, forward curved or back curved sparse blades. Condenser fans are of axial type and are chosen as quiet high efficiency. Condenser and evaporator coils are specially designed and feature as copper tube aluminum fin. Scroll and semihermetic compressors are used in single and tandem connection according to the capacity requirement in the cooling cycle. Roof-top air conditioners are used in hypermarkets, shopping malls, cinemas, show centers, educational institutions and factories with many industrial facilities

COOLING AND HEATING In the roof-top air conditioners where standard cooling and heat-pump cycle is used, draer set with exchangeable gland, liquid glass, four-way valve, expansion pressure reducing valve, liquid holder, oil separator, gas tank, mechanical check. The use of various elements, such as the valve element and the combined automatic, improves performance as well as the use of more diverse elements increases performance, as well as more durable and economical bit operation. Due to the speed adjustment of the condenser fans, it provides the possibility of cooling at low and high outdoor temperatures by producing as much flow as the system needs. Maintaining the condenser pressure above a certain level is vital for the healthy operation of the compressors. Thanks to the automatic reset pressure regulator placed at the condenser outlet, a hor fan can control the capacity in itself.

FANS Imported fans with curved front blades or sparse blades with backward curves are used. Pressure losses are calculated in order to overcome the suction and fresh air resistances. Used electric motors are used as Gamak or equivalent. Suction and discharge surfaces of Fanmak roof-top air conditioners can be made on the sides or at the bottom of the device. 

ECONOMIC MODE In places where cooling is required at low outdoor temperatures, the compressor is deactivated in order to reduce consumption when the outdoor temperature is below 180 ° C. The force cooling damper opens with the signal received from the electronic board and allows cold air to blow into the room. This mode is generally preferred in winter or spring votes where processing rooms and electronic devices emit excessive heat

COMPRESSORS In Fanmak rooftop air conditioners, hermetic scroll or semi hermetic piston compressors are used in single or tandem connection. Harmless feon gases such as R40 / c or R 410 / A are used as refrigerants. The compressors are protected by overheating thermistors and overcurrent thermals. Special rubber absorbers are mounted to the central body. Special vibration pipes are used to prevent transmission of vibrations from the pistons and scroll mechanism to the body. Sap-cooling or power control system is used for capacity control.
