Heating, ventilation and air-conditioning systems
The phase of implemented engineering sections necessarily implies the pre-selection process in choosing the technical solution and system design. Such an integrated package, as the heating, ventilation, and air conditioning systems always require highly qualified and responsible engineers. The energy consumption of the facility overall and comfortable working conditions for personnel are conditional upon the correctness of the project. The above-mentioned systems are always considered as a whole because of interlinkages between its output parameters in the design. What does it mean? The amount of heat gain from the heating system, for example, will affect the capacity of the air-in heater in the ventilation system, and the amount of heat in transferred air shall be offset by the heating system. Conditioning system can work in reverse flow during the cold season, thus reducing the system load. The channel air conditioner and the rooftop one, that serves as general ventilation along with refrigeration, in some instances, are desirable to integrate into conditioning system. Such examples of interdependence between the systems could be seen a lot, that’s why the HVAC systems require both competent and intelligent approach in selecting the technical decision for their implementation at each facility.
Well designed systems of heating, ventilation, and air conditioning will ensure comfortable working conditions for personnel, healthy microclimate, and high labour productivity. But energy-saving and emission reduction is an increasingly serious problem lately. The ventilation, cold and heat supply systems include the great potential to promote energy-efficient solutions since they occupy the lion’s share of the overall power balance of the building. The appropriate institutions and communities (ASHRAE, Eurovent, etc) dealing with this problem have been established in the USA and Europe. New directives, standards, and requirements are issued regarding the energy efficiency overall and the equipment used in commercial and residential property. This is why it’s essential that design and engineering companies introducing efficient technical solutions should be qualified at the highest modern standards and demands in the climate system industry. Only in this case, the Customer could benefit from the implementation of modern technical solutions, and the system could remain truly effective
