Features:
Package air conditioner is a bigger version of the window air conditioner. However, unlike window air conditioner or PTAC units, it has a higher cooling or heating capacity and is usually able to cool an entire house or a commercial building. The nominal capacities ranges from 3 tonne to 15 tonne.
The conditioned air are transferred to the space to be conditioned through ducting which is usually hidden in the ceiling and wall of the building. The unit is placed outside the house, a special room in a building or even on top of a roof. This unit is factory assembled and skilled technicians are needed to install this type of unit.
Protection devices such as High/Low pressure switch, overload relays for all motors, water flow and air flow switches are included in the units. The compressor have winding protection thermostat built into the winding to disconnect the circuit in the event of overheating.
There is an interlocking circuit with the evaporator fan motor starter to ensure that the compressor can only start if the fan motor is running.
Featuring an elegant design and high-end cooling, our Cassette Air Conditioners are the perfect answer to today’s cooling needs. Their multi airswing control provides multiple patterns to deliver maximum comfort. They are designed with unique "round" side contour and new LED light location to give your overall décor a nice value addition.
Cassette units are fairly unobtrusive and come in a range of sizes and capacities, so you have a reasonable amount of freedom when choosing where to install one. Generally speaking, cassette units are more appropriate for larger areas though. Because they take up a fairly large amount of space on the ceiling – and because the ceiling is normally composed of beams and joists, you will need to consult an expert installer to figure out exactly where you can safely mount one. As a general rule, a location that allows for clear, balanced air flow is also suggested for cassette units.
VRF are typically installed with an air conditioner inverter which adds a DC inverter to the compressor in order to support variable motor speed and thus variable refrigerant flow rather than simply perform on/off operation. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at load conditions. Heat recovery VRF technology allows individual indoor units to heat or cool as required, while the compressor load benefits from the internal heat recovery. Energy savings of up to 55% are predicted over comparable unitary equipment. This also results in greater control of the building's interior temperature by the building's occupants.
VRF come in two system formats, two pipe and three pipe systems. In a heat pump two pipe system all of the zones must either be all in cooling or all in heating. Heat Recovery (HR) systems have the ability to simultaneously heat certain zones while cooling others; this is usually done through a three pipe design, with the exception of Mitsubishi and Carrier, whose systems are able to do this with a two pipe system using a branch circuit (BC) controller to the individual indoor evaporator zones. In this case the heat extracted from zones requiring cooling is put to use in the zones requiring heating. This is made possible because the heating unit is functioning as a condenser, providing sub-cooled liquid back into the line that is being used for cooling. While the heat recovery system has a greater initial cost, it allows for better zoned thermal control of a building and overall greater efficiencies. In heat recovery VRF systems, some of the indoor units may be in cooling mode while others are in heating mode, reducing energy consumption.
A fan coil unit (FCU) is a device that uses a coil and a fan to heat or cool a room without connecting to ductwork. Indoor air moves over the coil, which heats or cools the air before pushing it back out into the room. FCUs can be less expensive to install than ducted systems, and are available in ceiling, floor-mounted and freestanding configurations.
FCU systems are of average efficiency only but if well maintained and operated can produce a good level of efficiency. Each FCU is provided with a small supply of outside air to ensure adequate ventilation. The advantages or disadvantages of this system are:
fan coil units by Cool Earth HVAC Engineers carry the flexibility of adapting to a wide range of space requirements, installation configurations and usage applications. These units have the versatility to match different interior designs while saving more space.
