Ductless mini split air-conditioners are relatively new to North America. However, they are the most commonly used system of air conditioning throughout the rest of the world. Ductless systems are also referred to as 'zone systems.' Understandably, ductless split air conditioning systems are becoming more popular in homes and offices, even when they are equipped with advanced central air conditioning system. By providing zone cooling, Ramsond ductless split system air conditioners save energy, since only the rooms that are occupied and used need to be cooled/heated. Simply stated, they cool/heat the 'zone' or the area in which they are installed. They require no expensive ductwork installation. This is the reason that they are far more efficient than conventional air conditioners. You can turn on the system when you want to use the area/zone and when not in use, the system can be simply turned off, saving electricity and money. Operating costs are much lower than those of central systems that cool every room, whether or not the room is in use. So, with a ductless system you can control the temperature of a zone where it is located. Therefore, you have the benefit of cooling only the room that you want, while leaving the central AC system off.

Ductless mini split system air conditioners combine the zoning flexibility of a conventional room unit (a single air-conditioner installed through a wall or a window frame) with the whole-house cooling potential of central systems. Like central systems, they have two main components: a compressor/condenser (outdoor unit), as well as an air handling unit (indoor unit/evaporator), which contains an evaporator and a fan. All Ramsond models are also equipped with heat pump, providing both summer cooling and winter heating.

The new Ramsond 74GW3 Ductless Mini Split Air Conditioning System, provides highly efficient and reliable cooling as well as heating for the winter. By setting the AC system in HEAT MODE, the heat pump is automatically activated. Heat-pump, by way of a reversing solenoid valve, reverses the flow of refrigerant and provides heating in the winter. Heat pumps are the most efficient mechanism of heating. However, heat pump split system are only operational to ambient temperature of 20 degree Fahrenheit. This means most heat pump systems will not produce heat at temperatures below 20 degrees Fahrenheit. Ramsond air conditioners, however, utilize the most advanced heat-pump technology, combined with the best available refrigerant to increase the heating capacity of the heat pump. This means that Ramsond units will provide sufficient heat, via heat pump at temperatures as low as 10 degrees Fahrenheit.

The new 74GW3 ductless split system is additionally equipped with back up electrical heating. Electrical heating does not have the limitations associated with heat pump. Therefore, regardless of the outside temperature, the electrical heat will work. Therefore, with this back-up electrical heat system, you can provide sufficient heat, regardless of outside temperature. This unique feature, among others, sets Ramsond ductless air conditioning systems in a class on its own when compared with other systems currently available in the market.

Ramsond's innovative QUICK-INSTALL™ system has now made the installation of its new range of ductless mini split systems even simpler than before. The new QUICK-INSTALL™ system incorporates the following features:

• Pre-wired indoor unit
• Pre-wired outdoor unit
• Quick-Connection terminals for the connecting the outdoor unit to the indoor unit
• Pre-flared, flanged, insulated Line Sets (Connecting Pipes) - No need for welding or soldering
• Pre-charged System (R410) - No need to charge the system
• Complete installation kit and hardware (Rubber Pads, Pipes, Drain Hoses, Tape, Putty, Insulation, etc.)

With these features of the QUICK-INSTALL™ system, the installation time is cut in half because the indoor and the outdoor unit are pre-wired and equipped with a quick-connection terminal. The quick-connection terminals also eliminate many of the wiring mistakes during installation which lead to permanent damage to system. With the QUICK-INSTALL™system it is now much easier and cheaper to install these units. Both the indoor and the outdoor units are pre-wired and equipped with quick-connection terminals. .

Multi-Dimensional Dual Oscillating Louvers Air Delivery Technology

Multidimensional oscillating dual louvers of Ramsond ductless systems ensure the uniform flow of air throughout the room. By selecting the 'SWING' feature on the wireless remote control, the louvers will continuously move in a uniform up/down movement to evenly spread the cool/hot air. They same feature would allow the louvers to be set in a stationary, single direction position which will focus the flow of air to a particular area of the room.

Ramsond ductless split air conditioners systems are the most complete systems available in the market. No other system in the market today comes with a such complete set of features and accessories.
