How does an HVAC system work?

HVAC system

According to Grandview hvac services experts, an HVAC (heating, ventilation, and air conditioning) system is an air conditioning and ventilation system. As an air conditioning system, it acts as heating in winter and cooling in summer. Its purpose is to provide the user with an indoor environment whose temperature, relative humidity, and air purification are comfortable.

An HVAC system contains a gas that, when compressed, increases its temperature due to pressure. Once heated, it flows through a duct where it dissipates its heat. It then gradually cools down until it is transformed into a low-temperature liquid. This liquid moves through an expansion valve and evaporates into a cold, low-pressure gas. It then flows through a duct absorbing the internal or external heat of the environment. It is then expelled through vents. This process runs uninterrupted while the system is in operation. Some designs have thermostats that stop the process or put it on standby.

One issue that should not be overlooked is that HVAC systems must ensure users’ safety and well-being and provide optimum thermal comfort. Therefore, the relevant maintenance and sanitation actions must be carried out by Grandview hvac services professionals to ensure that the air inside the air-conditioned enclosures is a quality air that does not endanger people’s health.

Aspects to take into account when installing an HVAC system

– We must ensure that the installation design has taken into account the adequate cooling capacity and correct air distribution (one of the most common complaints is direct and annoying air currents).

– It is essential that the system’s design is adapted to the use of the air-conditioned enclosure. The air conditioning design of a house is not the same as that of an office.

– The system must be adequately maintained and cleaned, taking into account the requirements of current regulations. It should be remembered that deteriorated and dirty ducts are among the causes of various discomforts that occupants may suffer: allergies, coughing, throat and eye irritation, bad smells, etc. Particular emphasis should be placed on the condition and replacement of the filters, as they are responsible for purifying the air by filtering pollutants. Also, the state of the condensation trays and ductwork, remembering that the accumulation of water inside them must be avoided (stagnant water is a breeding ground for the proliferation of bacteriological microorganisms).

Due to the need to reduce the energy bill and thus comply with your ethical responsibility in terms of sustainability and the environment, it is urgent to change the paradigm and gradually dispense with traditional air conditioning systems. Most of them are highly inefficient from an energy point of view. There are currently passive systems capable of reducing energy dissipation from our homes’ interior, thus reducing the use of these conventional air conditioning systems. These are hermetic and airtight controlled mechanical ventilation systems that, thanks to the heat recuperators they incorporate, can provide our interiors with healthy indoor air (free of impurities) without compromising thermal comfort.
