SECTION OF THE ROTARY HEAT EXCHANGER WITH THE HEAT PUMP: ideal solution targeting multiple goals
In conventional design of air-handling and heat-ing-cooling system several units are used: either chiller or condensing unit are combined with the main air handling unit or additional parts are inte-grated. Often both units are ordered from differ-ent suppliers, thus, this requires additional costs for installing and commissioning. Combination of rotary heat exchanger and heat pump offers new opportunities in design of modu-
lar units. The unit can work in winter and in sum-mer. When the unit runs in summer mode the supplied air is cooled using rotary heat exchanger first and then, additionally, using heat pump. The reverse process is used when the unit works in winter mode – the supplied air is heated.The most important thing is that the unit is fac-tory adjusted and tested. This minimizes efforts required on site.

EFFICIENCY ROTOR VS. ROTOR WITH HEAT PUMPWhen specific models are discussed, the advantage of the rotor with the heat pump becomes obvious. We have compared 5000 m3/h unit working in Central European weather conditions, where the winter temperature is as low as -12°C, and as high as +28°C in summer.
The section saves energy used for air cooling and heating. Without a heat pump, the additional energy for cooling and heating would be required and energy costs would be higher.

TECHNICAL INFORMATION
STRUCTURAL SCHEME OF WORKING UNIT
The heat pump consists of the following main components: variable speed compressor, evaporator, conden-ser, electronic expansion valve. The operation of these components altogether is consistent, so the unit can be controlled smoothly. All system com-ponents are interconnected using copper pipeline
inside the unit. The unit is suited for use of R410A type environment friendly refrigerant. Double protection is integrated into the heat pump. The control equipment of the heat pump is fully com-patible with the main controller of the air handling unit.
