Due to advancements in technology, trends in different fields of life have been going through changes. Thanks to technology, we now have advancements in the construction and building fields. We have different types of equipment for cooling buildings. There are many companies which provide cooling systems for residential and commercial buildings. Let us shed light on popular controls for buildings.
HVAC is a system which uses electricity to keep the room temperature moderate as per your requirement. The system consists of different types of equipment. Each of them works in a combination to maintain the average room temperature. The whole system is called HVAC control, meaning Heating, Ventilation and Air Conditioning. This system is an integral part that you can use to control the temperature in your home.
Types of HVAC Control
When we are constructing a building, we want it to be perfect. Mechanical engineering plays an essential role in building construction. When you or an engineer is constructing or designing a building, you should know the different types of HVAC controls.
1- Heating and Air conditioning Split Systems
This system consists of an outdoor unit. The outdoor unit has a compressor and a condenser. An indoor unit is also part of the whole system, which consists of the blower and evaporator coil. Due to this combination, it is known as a split system. The split system air conditioning is the most popular type of heating and air-controlling systems in the buildings. (We should note here that the indoor unit has a connection with a heat pump or a furnace.)
As you observe the split system, here are a few specifics:
- Outdoor unit to building – the compressor, electrical components, fan and the condenser coil
- It circulates from, and to, the outdoor and indoor unit by using a series of pipes
- Evaporator coil – which is above furnace inside the building
- Blower – to send warm air over the cold evaporator coil to absorb heat
- Duct – to carry air throughout the whole building
- Thermostat – to control the temperature
2- Hybrid heat Pump Systems
In this heat hybrid cooling and heating system, we use a heating pump in combination with the furnace. This combination with a furnace will burn the fuel oil, propane or natural gas. Heat pumps are a type of air conditioner. They can increase the room temperature by working in a reverse mechanism. This is a perfect device that can cool and heat your room efficiently.
*Please note that if the temperature is lower than 40 degrees, the heat pump won’t be effective. In that particular situation, the furnace will begin the heating.
If you are feeling a high level of cold temperature, the heat pump will take the heat out of the outer air to transport inside the building. During the summer season, it will work like a regular air conditioner. So, by using a single product, we can enjoy energy savings for the whole year.
If we are looking for an ideal system, it will consist of:
- Heat Pump
- Furnace and evaporator coil
3- Ductless Mini-split Heat Pump
We can use this particular type of duct-free HVAC system when the conventional ducted system doesn’t work at our buildings. Further, these systems can also be an excellent complement for the existing ducted systems.
As we discuss their installation, we will find out that they are usually installed into the area of the building that needs cooling and heating. A point to note here is that we can have four zones for a single outdoor unit.
A ductless mini-split heating pump system will consist of:
- Heat pump: It will comprise of condenser, compressor and a fan.
- Wires and Tubing
- Thermostat (control panel)
4- Packaged Heating and Air conditioning systems
This system is comprised of a condenser, an evaporator and a compressor. It is an all in one unit. The ideal location for the system is near the foundation of the building or the roof.
If your building lacks a proper space for split systems and their components, this system is ideal for you. The system is also famous for use in commercial buildings. It also includes furnace for heating and electric coils.
A packaged HVAC system will include:
- An air conditioner or heat pump with a combination of the evaporator or fan coil
- Control interface or a thermostat
- Optional tools like cleaners, ventilators, air purifiers, etc.
