HVAC

Introduction

There are a number of new and innovative technologies, which have the potential to reduce energy consumption greatly. The essence of HVAC (Heating, Ventilation, and Air conditioning) concept lies in keeping away from extremes i.e. to customize temperature level, air quality, air conditioning, etc. to work at an optimum level and thereby reducing operation cost on energy. The HVAC system is also known as climate control. This is because these three functions are essential in maintaining comfort in every dwelling. A well-selected and installed HVAC system can greatly enhance the comfort, productivity, improving performance and has direct impact on people’s health. Likewise, a poorly selected system will cause endless headaches for the facility executive, whether they’re hot/cold calls, indoor air quality problems or astronomical energy bills. Energy conservation and reutilization of exhaust energy is gaining momentum in HVAC operations.

Brief Description

Three Functions of HVAC:

Heating is significant in maintaining adequate room temperature especially during colder weather conditions. There are two classifications of heating: local and central. The latter is more commonly used because it is more economical. Furnace or boiler, heat pump, and radiator make up the heating system.

Ventilation, on the other hand, is associated with air movement. There are many types of ventilation, but they all function similarly. Ventilation is necessary to allow carbon dioxide to go out and oxygen to get in, making sure that people are inhaling fresh air. Stagnant air causes the spreading of sickness, usually airborne, and allergies. But it is also essential to maintain an efficient ventilation system, especially in the attics. Insufficient ventilation usually promotes the growth of bacteria and fungi such as molds because of high humidity. It will also decrease the effectiveness of rafter and roof sheathing insulation because of water vapor condensation.

The air-conditioning system controls the heat as well as ventilation. They often come in different sizes. Most air conditioners have large air ducts, so it is better to check out the building first to see if they can be installed. Or else, you can use the split system or remote coils. It is necessary, though, that air ducts are properly cleaned. Pathogens thrive in dirty air ducts. Return-air grills are also vulnerable to chemical, microbiological, and radiological elements. Thus, HVAC return-air grill height should be that it is not accessible but visible for any observation.
