There are many benefits of living at a high altitude, from crisp fresh air to general healthiness to dazzling views, and so on. You can visit here to learn how high-altitude living can improve a person’s health. There are two disadvantages that you should consider being design and construction, including your heating and cooling systems. Therefore, in this article, we will be discussing things you need to know about heating and cooling services at high altitudes.
Does Altitude Affect Cooling Systems?
The answer to this big question is a yes. However, the effect is not as much as you would expect, and it can even be not very important at specific feet. Your HVAC unit cooling performance is often affected by less than three percent.
Furthermore, below 10,000 ft, the effect is so tiny you can overlook it. However, this doesn’t take away the fact that altitude affects cooling systems. Some of the things that cause this influence include dew point temperature, enthalpy, air density, etc.
We know that higher altitudes have less dense air, but how does this impact your HVAC systems? The most significant impact may be the fan’s performance since they are at standard conditions of 14.696 psi and 70°F.
Fans are devices known to be constant-value; therefore, as higher altitudes cause a decrease in air density, the fan’s mass flow decreases.
HVAC equipment like air-cooled chillers and rooftop units have fans. Therefore, we need to modify the equipment for these high-altitude situations. Therefore, many manufacturers have engineers proficient at handling these issues, so the produced systems can withstand the altitude issues. Special drive package, motors, and fans are often used to make up for the conditions.
Also, most HVAC companies have personnel that can adequately handle heating and cooling issues related to just how high up a building is.
Therefore, if you need to hire this service, you need to be sure they can handle the job. Visit Bosque HCP – Albuquerque HVAC Contractor to learn more about heating and cooling services at a high altitude.
Why Height Affects Heating
The air at pretty high altitudes is thinner and carries less heat. Also, the decrease in the oxygen levels and air pressure equally affects the heating function of your unit.
Therefore, to maintain efficient heating under these conditions, your HVAC professional must use the right equipment.
Gas Heating Units
When it comes to altitudes and HVAC units, gas heating units are pickier. They need to increase their BTUH output to suit the winter colder temperature. Furthermore, to ensure the proper functioning of the team, it has to be modified in certain aspects.
These types of units often have gas valves and orifices. The HVAC professional would have to change the orifice size for higher altitudes. Also, the gas valve has to be adjusted since it is already set at sea level by the manufacturer.
Without adjustments, it may result in under or over-firing, the unit’s heat exchanger may soot, or the unit may shut down, resulting in more service calls and more costs. Therefore, either avoiding a gas heating, or the professional employed for its installation has proper knowledge about it.
Air Conditioning Contractors of America’s Manual S and Original Equipment Manufacturer
When the HVAC professional wants to determine appropriate heating settings and devices, he can consult either following.
You can read this article to learn more about the ACCA Manual S. The OEM gives information about the unit’s model, required accessories, and make. The professional will determine the heating system’s output and input capacity above sea level when considering these two.
In this article, we have discussed essential things about heating and cooling systems at high altitudes. Topics discussed in this article range from why height affects heating systems, if altitude affects cooling systems, and so on.
