Air conditioning

Air conditioning is a mechanical process of removing or transferring heat from a designated indoor room and rejecting the heat outdoors. A medium such as refrigerant is commonly used as the vehicle to transport or move the heat from indoors to the outdoors. The main indoor component of an air conditioning system is commonly referred to as the "evaporator"/blower section. The outdoor unit is commonly referred to as the "condenser" section.

Space cooling vs spot cooling:

Space cooling: Air conditioning of an entire room or area. i.e. Office, bedroom.
Spot cooling: Air conditioning a small area within a room. (does not cool entire room) i.e. work station.

Coil:

The appearance and function of an air conditioning coil is very similar to the radiator in your automobile. In most air to air air conditioning systems there are two coils. An evaporator coil and a condenser coil. The coils in FREECOM® air conditioning products are engineered for maximum efficiency using special proprietary Ripple Finned Copper Tube with Louver Fin design.

Evaporator (indoor unit):

Refrigerant from the condenser is circulated through tubes inside the evaporator. A fan circulates indoor air through the evaporator's coil. As the air passes through the coil, heat is removed from the air by the refrigerant. The "heated" refrigerant is circulated back to the condenser.

Condenser (outdoor unit):

Refrigerant from the evaporator is circulated in tubes inside the condenser's coil. A fan circulates outdoor air through the condenser coil and "removes" heat from the refrigerant. The refrigerant is then circulated back to the evaporator. The circulation of refrigerant is a continuous cycle from and to the condenser and evaporator coils.

Refrigerant:

A special chemical manufactured primarily for use in air conditioning and refrigeration systems. Used as a vehicle or medium to "collect" and transfer heat.

Compressor:

A motor device used primarily in air conditioning and refrigeration systems to circulate or "pump" refrigerant. FREECOM® products are manufactured with world renowned Matsushita brand energy efficient rotary compressors. Matsushita compressors are the most reliable compressors available worldwide.

Fan Motors:

Fan motors are used to circulate air across and through the evaporator and condenser coil. The most efficient and reliable products utilize a designated fan motor for the evaporator and condenser. FREECOM® models RCS-M2000T and RCS-S3000T utilize designated (dual) fan motors.

Condensation:

An air conditioner not only removes heat but also removes or condenses humidity or water molecules from the air. This water is commonly referred to as condensation. This function is commonly referred to as dehumidification.

BTU:

British Thermal Unit: Measurement used to determine cooling capacity of an air conditioner. The number of BTU's you will require to air condition a specific area or space is based upon the amount of heat (cooling load) that has to be removed from the area that you want to air condition. To calculate cooling load a number of factors must be considered. Such as geographic location, building type, exposure to sunlight, number of windows, number of persons occupying the space and appliances/equipment located in the space.

If the air conditioner that you purchase has insufficient BTU capacity (under sized), the unit will operate continuously and cooling will be ineffective.If the air conditioner has excessive BTU capacity (over sized), the unit will short-cycle and not remove the humidity resulting in a clammy ambient.

To select a properly sized (capacity) air conditioner for your application, we recommend that you consult with an air conditioning trade professional or reputable dealer.

EER Energy Efficiency Rating:

A formula to determine energy consumption or efficiency of an air conditioner. The higher the EER the more energy efficient the product. To calculate basic EER divide the cooling capacity by the watts input. Example: The cooling capacity of the FREECOM® model RCS-M2000T is 8000BTU and the watt input is 800. 8000BTU divided by 800 watts = 10 EER

PC (Electronic) Circuitry:

Printed Circuitry is found in all modern appliances. PC circuitry has been the major contributing factor in reducing the physical size and weight of appliances and has substantially increased long term reliability and efficiency. PC technology has replaced and surpassed obsolete mechanical devices such as unattractive knobs, dials and noisy relays.

All FREECOM® products utilize state of the art PC technology and circuitry.

Thermostat:

A thermostat is a device that measures ambient air temperatures and regulates the operation of the air conditioner. Better products are designed with adjustable thermostats. A thermostat will maintain a desired, constant room air temperature. FREECOM® models RCS-M2000T and RCS-S3000T are equipped with internal, PC technology soft touch adjustable thermostats.

Electrical requirements:

Basic electrical requirements are measured in voltage and amperage. Voltage: The standard household outlet voltage is 110 volt and is suitable for all FREECOM® products. Note; Central or ductless mini split systems may require installation of a designated 220 volt electrical system. Amperage (amps): Is the electrical "capacity" of a device. The average household outlet has a capacity rating of 15 - 20 amps. Assuming that no other appliance is sharing an outlet, this standard capacity is usually sufficient for a FREECOM® portable air conditioner.

Air to air design:

Ambient or outdoor air is used as the medium to remove/reject heat and is circulated over both the evaporator and condenser coils.

Buyer beware! If a portable air conditioner is not an air-to air design it may require that you add water or is depended upon condensation to maintain higher cooling capacities. Without water, products of this type will experience a decrease in cooling capacity of 30% or more.

Caution is also recommended for products that exhaust condensation water through the air hose. A kinked or broken hose could result in flooding or water damage to your home/office.
