FEATURES / BENEFITS
AN INEXPENSIVE AND CREATIVE SOLUTION TO DESIGN PROBLEMS.
The 38HDF(QRF) / 40QNC (QNQ) series duct-free split systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires.
The fan coil is mounted on the wall, near the ceiling. This selection of fan coils permits inexpensive and creative solutions to design problems such as:
- Add-ons to current space (an office or family room addition)
- Special space requirements
- When changes in the load cannot be handled by the existing system.
- When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork.
- Historical renovations or any application where preserving the look of the original structure is essential.
LOW SOUND LEVELS
When noise is a concern, the duct-free split systems are the answer. The indoor units are whisper quiet. There are no compressors indoors, either in the conditioned space or directly over it, and there is none of the noise usually generated by air being forced through ductwork.
When sound ordinances and proximity to neighbors demand quiet operation, the 38HDF/QRF unit is the right choice: The advanced, horizontal blow-through airflow design distributes air more evenly over the coil.
If security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to prevent intruders from crawling through ductwork. In addition, since 38HDF/QRF units can be installed close to an outside wall, coils are protected from vandals and severe weather.
The small footprint of the outdoor unit provides additional benefits. Because they require minimal service and airflow clearances, the outdoor units can be located virtually anywhere - on the ground, roof, balcony, under a deck, or even mounted to an outside wall.
The indoor hi-wall units are simple to install. A mounting bracket is standard with the indoor units and only control wires and piping need to be run between indoor and outdoor units. These units are fast and easy to install ensuring minimal disruption to customers in the home or workplace. This makes the 38HDF (QRF) /40QNC (QNQ) duct-free split systems the equipment of choice, especially in retrofit situations.
SIMPLE SERVICING AND MAINTENANCE
A single panel provides immediate access to the isolated compressor and control compartment, allowing a service technician to check the unit operation without a loss of condenser airflow. In addition, the blow-through design of the outdoor section means that dirt accumulates on the inside surface of the coil. Coils can be cleaned from the outside using a pressure hose and detergent without removing grilles or using fin combs.
On all indoor units, service and maintenance expense is reduced due to easy-to-access cleanable filters. In addition, these high wall systems have extensive self-diagnostics to assist in troubleshooting.
Duct-free split system indoor and outdoor units are designed to provide years of trouble-free operation.
The high wall indoor units include protection against freeze-up and high evaporator temperatures on heat pumps.
The condensing units and heat pumps are also protected. There is a 3-minute time delay before the compressor will re-start. An oversized accumulator, high and low pressure switches ( or liquid line pressure switch on the heat pump), and compressor internal overload protection will ensure a reliable system that is ideal for light commercial applications.
INDIVIDUAL ROOM COMFORT
Maximum comfort is provided because each space can be controlled individually based on usage pattern. The air sweep feature provided permits optimal room air mixing to eliminate hot and cold spots for occupant comfort. In addition, year-round comfort can be provided with heat pumps.
The duct-free split system design allows individual room heating or cooling when required. There is no need to run large supply-air fans or chilled water pumps to handle a few spaces with unique load patterns. In addition, because air is moved only in the space required, no energy is wasted moving air through ducts.
The high-wall units have microprocessor-based controls to provided the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between user and the unit.
A variety of accessories simplify the installation process and help meet system requirements and weather conditions.
All systems are listed with AHRI (Air Conditioning, Heating & Refrigeration Institute), and UL.
