Heating, Ventilation and Air Conditioning System Solution

    1. Solution Overview
    HVAC is the technology of indoor and vehicular environmental comfort. Its goal is to provide indoor air quality.
    HVAC (stands for Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the blower).
    HVAC is important in the design of medium to large industrial and office buildings such as healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
    Ventilating or indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.
    Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural types.

    3. Customer Benefits
    a. Indoor Air Quality
    The EPA states that indoor air quality is two to five times worse than outdoor air, mostly since the air flow is congested. This polluted air within your home can cause colds to linger longer and allergies to be more severe. An HVAC system can improve air quality by constantly exchanging the indoor air with fresh, outdoor air that is also filtered for the best quality possible. 
    b. Energy Conservation
    The initial investment for an HVAC system may be higher than the typical gas furnace, yet the long-term, energy saving benefits are noticeable each month. The HVAC system has both heating and cooling in one unit. This alone saves construction space, installation time and fees, and required power usage. The system is also run by renewable energy, sometimes in the form of solar panels. Energy conservation is even better since the coolant is nonchlorine-based, which happens to deplete the ozone layer.
    c. Moisture Consistency
    Whether you live in a climate that changes drastically every three to four months, or you live in a climate that remains constant, your home is always subject to moisture retention. Since air inside the home does not circulate properly and is rarely exchanged with cooler, drier air outside when applicable, your home may easily grow mold or mildew inside walls and under floors. To reduce the chances of mold growth, which also causes health concerns and structural damage over time, the HVAC system consistently pulls warm, moist air out and sends dry, cool air inside in an exchange.
