Rufftop

Rooftop air conditioners installation peculiarity

The unit does not require the construction and use of a special refrigerant piping. It is installed at the highest point on the roof of the building, (hence the name rooftop air conditioner) or on the side of the building. Air supply is performed with the help of duct systems or by means of air ducts. Construction features of roof tops The indispensable components of roof tops are: A closed-circuit refrigeration circuit. Scroll compressors, due to their design working almost silently. The protection system, functioning in automatic mode. Unit includes a heat exchanger for air heating and a thermostatic expansion valve. The chambers of the fresh outside air supply which are equipped with an air damper. The fresh air stream from the street is drawn through a grid into the mixing chamber (1) where it joins the recirculation air and flows through the filter to the heat exchanger (3) into the room. The constantly moving air dampers (4) create the necessary proportion of mixed air. The heating section (5) is used to warm the cold air when it is cold and can be heated by gas, electricity or water. The condenser (6) is cooled by the blown air. The gas heating contributes to the low inertia of the equipment due to the absence of an intermediate heat accumulator; a closed burner is used for heating, which heats the air at high speed thanks to its closed design, it has no open contact with the fire and waste products obtained from gas combustion. The cold output of the Rufthop, ranges from 10 to 480 kW. Heating ranges from 40 to 235 kW. For silent work are used scroll compressors equipped with protection against overloads and pressure surges, the compressors are made of two-stage design. Cooling is performed by axial fans, which do not create noise. As fuel, liquid fuel as well as methane and propane can be used. To save energy, the unit is equipped with temperature sensors, automatically controlling the operation of air valves. The cooling is done by axial fans, which do not create noise.

Air conditioner control

The control function is entrusted to the main compressor installed in the control cabinet, it controls an electronic system composed of contact panels connected to switches connected to a microprocessor and a thermostat that optimizes the operation of the air conditioner. The electronic control system performs the functions of: 1.Turns on the compressor for the cooling circuit 2.Turns on the burner of both stages 3.Actuates air dampers for air intake and mixture 4.Switches the dampers depending on whether the cooling or heating circuits are engaged.

Advantages of a roof top air conditioner Compact small size. Independent use of air. Capacity varies depending on the programmed temperature. Low power consumption of electric motor. Variety of gas fuels. Safe compressor mechanism. Good and efficient filtration system. Practically noiseless operation.

Single monoblock design allows quick and easy installation. The use of a ruftop in the building makes the presence of a heat boiler not a prerequisite for the design of the building
