This selection of fan coils permits inexpensive and creative solutions to design problems such as:S Add−ons to current space (an office or family room addition)S Special space requirementsS When changes in the load cannot be handled by the existing systemS When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork SHistorical renovations or any application wherepreserving the look of the original structure is essential.The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork. These compact indoor fan coil units take up very little space in the room and do not obstruct windows. The fan coils are attractively styled to blend with most room decors.Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels.LOW SOUND LEVELSWhen noise is a concern, the ductless 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.SECURE OPERATIONIf 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 outdoor units can be installed close to an outside wall, coils are protected from vandals and severe weather.FAST INSTALLATIONThis compact ductless system is simple to install. A mounting bracket is standard with the indoor units and only wire and piping needs to 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 ductless systems the equipment of choice, especially in retrofit situations. SIMPLE SERVICING AND MAINTENANCE Removing the top panel on outdoor units provides immediate access to the control compartment, providing a service technician access to check unit operation. In addition, the draw−thru design of the outdoor section means that dirt accumulates on the outside surface of the coil. Coils can be cleaned quickly from inside using a pressure hose and detergent.On all indoor units, service and maintenance expense is reduced due to easy−to−use cleanable filters. In addition, these cassette systems have extensive self−diagnostics to assist in troubleshooting.BUILT − IN RELIABILITYDuctless system indoor and outdoor units are designed to provide years of trouble−free operation.The in−ceiling cassette units include protection against freeze−up and high evaporator temperatures on heat pumps.The condensing units on heat pumps are protected by a three minute time delay before the compressor starts the over−current protection and the high temperature protection.INDIVIDUAL ROOM COMFORTMaximum 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.ECONOMICAL OPERATIONThe ductless 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.EASY−TO−USE CONTROLSThe in−ceiling cassette has microprocessor−based controls to provide the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between user and the unit.FACTORY INSTALLED CONDENSATE LIFT PUMPCustomizing these ductless systems to your application is easily accomplished. The factory installed condensate lift pump on the cassette fan coil unit provides installation flexibility.OPTIONAL WIRED CONTROLLERAGENCY LISTINGSAll systems are listed with AHRI (Air Conditioning, Heating & Refrigeration Institute), and ETL.23MODEL NUMBER NOMENCLATUREQ C -SYSTEM TYPE Q = HEAT PUMP INDOOR FAN COIL TYPE C = CASSETTENOT USEDINDOOR UNIT40MB 30940 = FAN COIL UNITMB = MODELVOLTAGE3 = 208/230-1-60NOMINAL CAPACITY 09 - 3/4 TON 12 - 1 TON18 - 1-1/2 TONS 24 - 2 TONS36 - 3 TONS 48 - 4 TONSNOT USED- -Use of the AHRI Certified TM Mark indicates a manufacturer’s participation in theprogram For verification of certification for individual products, go to.4STANDARD FEATURES AND ACCESSORIESS Standard A AccessoryACCESSORIESINDOOR UNIT ACCESSORIESGrilleTo maximize shipping efficiency , the grille for the in−ceiling cassette is set up as an accessory.NOTE: Grille is required.5DIMENSIONSFig. 1 – Indoor Unit (Sizes 9−18)6DIMENSIONS − (CONT)32A B C DCapacity (Btu/h)24K mm 160 75 205 50 inch 6.30 2.95 8.07 1.97 36K mm 160 95 245 60 inch 6.30 3.74 9.65 2.36 48Kmm 160 95 287 60 inch 6.30 3.74 11.30 2.36Fig. 2 – Indoor Unit (Sizes 24−48)CLEARANCESFig. 3 – Indoor Unit Clearance7SPECIFICATIONSNOTE: Performance may vary based on the compatible outdoor units.

COMPATIBILITYNOTE: Backward compatible with 38MAQ Single Zone and 38MGQ Multi−zone Systems.8APPLICATION DATAUNIT SELECTIONSelect equipment to either match or handle slightly less than the anticipated peak load. This provides better humidity control, fewer unit cycles, and less part−load operation.For units used in spaces with high sensible loads, base equipment selection on the unit sensible load, not on the total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing the equipment.UNIT MOUNTING (INDOOR)Refer to unit Installation Instructions for further details.Unit leveling − For reliable operation, units should be level in all planes. Align and level the unit by adjusting the nuts and lock−nuts on the threaded hangers.Clearance − A minimum of 12 inches (304.8 mm) of clearance is required in the false ceiling.Unit location − Placing the unit in the center of the room provides the best air circulation and comfort. The unit return and discharge should not be obstructed by anything which may cause unit short cycling or air recirculation.Installation Template − Fan coil units are supplied with a cardboard template to help match the position of the hangers, refrigerant lines, condensate drain pipe and power supply cable. UNIT MOUNTING (OUTDOOR)Refer to the unit’s Installation Instructions for further details. Do not install the indoor or outdoor units in a location with special environmental conditions. For those applications, contact your ductless representative.SUPPORTAdequate support must be provided to support the weight of all fan coils. Refer to the Physical Data section for fan coil weights, and the base unit dimensional drawings for the location of the mounting brackets.SYSTEM OPERATING CONDITIONSDRAIN CONNECTIONSInstall drains to meet local sanitation codes. The in−ceiling cassette is supplied with a condensate lift pump that is capable of lifting the water 29.5in (750mm) above the top of the unit. A downward sloped condensate drain pipe can be used to dispose of water. REFRIGERANT LINESGeneral refrigerant line sizing:1.The outdoor units are shipped with a full charge of R410Arefrigerant.2.Refrigerant lines should not be buried in the ground. If it isnecessary to bury the lines, not more than 36−in (914 mm)should be buried. Provide a minimum 6−in (152 mm)vertical rise to the service valves to prevent refrigerantmigration.3.Both lines must be insulated. Use a minimum of 1/2−in.(12.7 mm) thick insulation. Closed−cell insulation isrecommended in all long−line applications.4.Special consideration should be given to isolatinginterconnecting tubing from the building structure. Isolatethe tubing so that vibration or noise is not transmitted intothe structure.9WIRINGAll wires must be sized per NEC (National Electrical Code) or CEC (Canadian Electrical Code) and local codes.

其优点包括维修费用低、运转距离较大、启动特性和调速特性优秀、调速性能好、调速范围广且平滑、过载能力较强和受电磁干扰影响小。
因此直流电机在各领域都有着广泛的应用。
早期的直流电机通过电刷进行换向，被称为直流有刷电机，但由于电刷在换向时会产生电火花，既造成了换向器的电腐蚀，还是无线电干扰源，会对周围的电器设备带来有害影响。
电机的容量越大、转速越高，问题就越严重。
因此安全可靠性使电机的使用受到了限制。
