CENTRAL AIR CONDITIONING HISTORY
The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking techniques of the time. Carrier treated the air inside the building by blowing it across chilled pipes. The air cooled as it passed across the cold pipes, and since cool air can’t carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature — and a new technology was born.
The major parts of a GOODMAN Air Conditioner manages refrigerant and move air in two directions: Indoors and Outside:
- Evaporator - Receives the liquid refrigerant
- Condenser - Facilitates heat transfer
- Expansion valve - regulates refrigerant flow into the evaporator
- Compressor - A pump that pressurizes refrigerant
The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. In between the two sets of coils, there’s an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas. The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.
FUJITSU Ductless Mini Splits makes it possible to heat and cool almost any application without the need of duct work, they save place, are energy efficient and offer superior comfort control, easy to install, easier to operate. Ductless Mini split systems incorporate intelligent control technology to make them more responsive to your needs. A smart inverter rotary scroll compressor technology reduces your energy consumption by one third compared to traditional AC.
The versatility and variety of applications for ductless split Air conditioning systems are virtually unlimited. They are an excellent choice for almost any spot –cooling or heating solution, new construction, central ac Multi-zone system; you can heat and cool multiple areas independently, or as supplemental systems. Applications include sun rooms, bedrooms, finished basements, as well as classrooms, hospitals, nursing homes, restaurants, hotels, computer rooms, offices, churches and a multitude of other light commercial applications.
About Duct-Free Systems
A duct-free system, also known as a “split” air conditioner system, is made up of or includes two components: an indoor unit to deliver conditioned air to the room, and an outdoor unit located outside of the house. Compact refrigerant lines run between the two units, eliminating the need for bulky ductwork. Duct-free systems are ideal for older homes that have no ductwork with hot water heating systems, adding room additions, or areas in homes that just never seem to be the right temperature or are never comfortable.
Duct-free systems are available in a range of sizes and styles–including systems that can heat and cool multiple rooms with a single outdoor unit to fit almost any need. The indoor units are available in many different types to fit with the look and feel of your home.
Duct Free Systems provide independent zoning and room by room temperature control.
FUJITSU “ducted” units can be installed beneath floors and attic areas. Insulated ducting moves cold and hot air to each room. This is a heat pump type system. During cold winter months it will provide warm air for heating. During hot summer months, unit will provide cold air for cooling. Ceiling or floor openings are applied. Registers installed in openings.
One ducted type unit is ideal for homes with hot water heating systems. Whereas, there is no ductwork within home. Single compact “ducted” unit can provide up to 26,000 btus of cooling for a designated area of building. These are very universal type units. Internal factory supplied water pumps are built-in unit for drainage.
