Features and benefits of central ventilation systems

3. In the central heating and cooling systems of chillers and boilers, rooftop packages, VRF and GHP devices that are used with fan coils and air conditioners, air humidity can be adjusted accurately and to the desired level. But in Airwasher, Zent and Econopack devices, due to the evaporative nature of the cooling process (with water spraying), air humidity increases.

4. Zent, ​​Econopack and Airwasher devices have fresh air entry channels from outside the building and heated and cooled air distribution channels in different partitions of a building. On the other hand, air conditioners that are connected to chillers, boilers, or VRF and GHP devices also have this capability, and in the fan coil system, a channel fan coil or duct fan coil can be used to bring fresh air into the building.

5. In terms of the type of energy consumed in central heating and cooling systems, all types of energy (electricity, gas, water) can be used. For example, heating and cooling in GHP is done by city gas (with a little electricity) and in devices like VRF by electricity alone. In evaporative systems such as Airwasher and Zent, ​​in addition to electricity, water is also used.

6. Central air conditioning systems have very powerful cooling and heating capabilities, and as mentioned, they are mostly used for large-scale applications, and in smaller sizes (for example, a unit with several rooms or halls), smaller models can be used. They are used like mini chillers and fan coils or split ducts.
