What We Do

/ HVAC

Central Air Conditioning

Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills)

carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.
Air conditioners help to dehumidify the incoming air, but in extremely humid climates or in cases where the air conditioner is oversized, it may not achieve a low humidity. Running a dehumidifier in your air conditioned home will increase your energy use, both for the dehumidifier itself and because the air conditioner will require more energy to cool your house. A preferable alternative is ade humidifying heat pipe, which can be added as a retrofit to most existing systems.

Split
Air Conditioning
A split air conditioner is a suitable alternative to wall, window, or centralized air conditioner systems. Often called mini-split, ductless split, or duct-free air conditioning, this system can adequately cool a standard-sized house without requiring extensive installation costs and efforts.

Components

A split air conditioner is made up of two primary parts that a very familiar: the evaporator and the compressor. Both of these elements exist is more common central air units and wall air conditioners. The difference with a mini-split system is that they are separated into two different, distant components, one being outdoors and one being indoors. The outdoor section is a compressor that initiates the cooling process, while the indoor component consists of an evaporator and fan.
The two sections are connected with a set of electrical wires and tubing, also called lines, used to transport air between the two sections. It’s these lines that allow the split AC to be considered ductless, and the fact that the wires and tubing are so small and discreet compared to large ducts is where the “mini” split name comes from.

/ Chiller

Industrial chiller selection

Important specifications to consider when searching for industrial chillers include the total life cycle cost, the power source, chiller IP rating, chiller cooling capacity, evaporator capacity, evaporator material, evaporator type, condenser material, condenser capacity, ambient temperature, motor fan type, noise level, internal piping materials, number of compressors, type of compressor, number of fridge circuits, coolant requirements, fluid discharge temperature, and COP (the ratio between the cooling capacity in RT to the energy consumed by the whole chiller in KW). For medium to large chillers this should range from 3.5 to 7.0, with higher values meaning higher efficiency. Chiller efficiency is often specified in kilowatts per refrigeration ton (kW/RT).

VRV
System
also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. Like ductless minisplits, VRFs use refrigerant as the cooling and heating medium. This refrigerant is conditioned by a single outdoor condensing unit, and is circulated within the building to multiple indoor units.

How does VRV work?

VRV is a technology that alternates the refrigerant volume in a system to match a building’s precise requirements. Only a minimum amount of energy is required for a system to maintain set temperatures, and ensure that it automatically shuts off when no occupants are detected in a room. This unique mechanism achieves more sustainability in the long run, as end users save on energy costs while reducing their system’s carbon emissions. With up to 64 indoor units connected to 1 outdoor unit, the VRV system operates similar to a Multi-Split system.
Each individual indoor unit determines the capacity it needs based on the current indoor temperature and requested temperature from the remote control (set point).
The total demand among all indoor units will determine how the outdoor unit adjusts
the refrigerant volume and temperature accordingly. By only supplying the cooling
or heating that is needed, the inverter compressor continues to save a large amount
of energy during VRV operation.

/ Maintenance

Professional Air Conditioner Inspection

There are a number of different types of AC units and air conditioner maintenance will depend on the type of unit you own.

Another important part of maintaining your AC unit is scheduling an annual air conditioner maintenance service—ideally before the cooling season begins—in order to make sure it is working as efficiently as possible. Aire Serv Total Comfort Tune-up will ensure that your air conditioner is in tip-top working shape and that it will last for years to come. Plus, our experts at Aire Serv can address smaller problems that could grow into larger and potentially costly issues in the future.
