Mitsubishi Electric indoor units are easy to install practically anywhere: Heat pump systems feature auto mode, which automatically switches between cooling and heating in response to the changing load in the space. Our systems are nearly silent; their fans deliver air quietly and continuously with only a gentle whoosh for constant circulation and filtration. For this reason, Mitsubishi Electric split-zoning systems have long been the choice in thousands of homes, churches, schools , and libraries across the U.S. and the world. SINGLE ROOM, WALL-MOUNTED HEAT PUMPS (cooling and heating) 9,000 to 33,200 Btu/h 14.5 – 21 SEER 8.2 – 10 HSPF Provides cooling and heating in a wide range ofcapacities Offers a WIDE Vane bottom outlet for a wider angle of airflow, 150° from left to right(on GA24/D30/D36 models) Our heat pumps are ideal for applications in the following spaces: Bedrooms, home offices, living rooms, dining rooms, bonus rooms, basements, kitchens, guard houses, and more

9,000 and 12,000 Btu/h 23 – 26 SEER 10 – 10.6 HSPF Quiet operation as low as 19dB(A) H2i high heat capabilities SINGLE-ROOM, HORIZONTAL DUCTED HEAT PUMPS (cooling and heating) If you are looking for discrete zoned comfort, then a short-run ducted unit is the right solution. As a stand-alone system or connected to a MXZ multiroom system, the SEZ ducted units provide energy efficiency, quiet operation, and a compact design for quick, easy installation either hidden in the ceiling or beneath the floor. Three of the 1:1 systems are ENERGY STAR certified , and two systems qualify for the federal tax credit. These systems provide customers with an environmentally friendly option that also gives them an installed look that is similar to what they are used to within their interior space. These models offer the added flexibility of working tandem with ductless models on the same MXZ multi-zone system, providing a wide array of installations options to best fit any application.

Provides cooling and heating in a wide range of capacities SINGLE-ROOM, LOW WALL or FLOOR-STANDING UNIT (For use with MXZ-B Outdoor Units only) Two outlet air vents: -Upper vent for cooling or heating -Bottom vent for heating only Flush and recessed installation of the unit is supported New to our lineup is a Low Wall or Floor-Standing model that can fit into those once difficult installations. These unites provide comfort in spaces such as finished attics with knee walls, basements with low ceilings, and glass-walled sunrooms. Mounted three inches above floor level, these models provide conditioned air from both upper and lower vents while providing direct front panel access to the filer for easy cleaning. The MFZ can even be recessed in a wall during installation provided proper clearances are maintained. Enjoy ideal levels of comfort in the rooms you use most with our multi-room system. Each room (zone) operates independently. People in different rooms – the kitchen, master bedroom, or living room – can enjoy temperature settings that make each of them most comfortable.

If you’re looking for a complete comfort solution for several different rooms, the MXZ multi-room system is the right choice. The system is flexible enough to conform to a particular cooling and heating need and offers numerous different indoor unit combinations. ac unit for rentIn addition up to eight indoor units can be connected to one outdoor unit. how much does the outside ac unit costNow with a SEZ horizontal ducted unit and a MFZ floor-standing unit homeowners can enjoy an even greater range of zoning options provided by an MXZ system.air handling units uk An MXZ multi-room system is an excellent choice for supplementing capacity to a current system, conditioning newly furnished spaces, or new additions and replacing a system within a home.

Homeowners can also benefit from lower energy costs year-round while staying comfortable thanks to Mitsubishi Electric’s energy-efficient technologies that are a part of every system that we make. About LG Air Conditioner When the cold or heat make home comfort a problem an LG air conditioner or heater is your solution. LG electronics applies their propritary technology on air conditioner and heat systems that allow you to take control of your home comfort heating and air conditioning needs. A ductless system, also known as a "split" air conditioner system, is made up of or includes two components: an indoor unit to deliver conditioned air to the room, and an outdoor air conditioner located outside of the house. Compact refrigerant lines run between the two units, eliminating the need for bulky ductwork. Ductless systems are ideal for older homes that have no ductwork, room additions, or areas in homes that just never seem to be the right temperature or are never comfortable.

LG ductless systems are available in a range of sizes and styles--including systems that can heat and cool multiple rooms with a single outdoor unit to fit almost any need. The indoor units are available in many different types to fit with the look and feel of your home. Whether you're creating a quiet, comfort controlled room, or simply want to heat or cool an area without expensive ductwork, LG's ductless systems set a new standard for efficiency, great looks and comfort. About LG Ductless Air Conditioners... LG understands that Life's Good and we should enjoy it to the fullest. Ductless Air conditioners are part of LG everlasting techonolgy upgrades with smart inverter compressors. "Read more about LG." Using air to heat buildings - temperature rise diagram Air heating systems may be cost effective if they can be made simple or if they can be combined with a ventilation system. BUT - be aware that due to the low specific heat of air the use of air for heating purposes is very limited.

Larger heat loads requires large volumes of air resulting in huge oversized ducts and fans. Transport of huge volumes of air requires a lot of energy.     Required Air Volume in an Air Heating System Required air flow rate in an air heating system can be calculated as L = Q / (cp ρ (th - tr))          (1) where L = air flow rate (m3/s) Q = heat loss covered by the air heating system (kW) cp = specific heat air - 1.005 (kJ/kgoC) ρ = density of air - 1.2 (kg/m3) th = heating air temperature (oC) tr = room temperature (oC) As a rule of thumb the air heating supply temperature should be in the range 40-50oC. The air flow should be in the range 1-3 times the room volume.  Equation (1) expressed in imperial units:  L = Q / (1.08 (th - tr))          (2) where Q = heat (btu/hr) L = air volume (cfm) th = heating air temperature (oF) tr = room temperature (oF) Online Air Heating Calculator  Q = heat loss from the building (kW)  ρ = density of air - 1.2 (kg/m3)  th = heating air temperature (oC)  tr = room temperature (oC) Air Heating - Temperature Rise Diagram The diagrams below can be used to estimate heat required to rise temperature in air flows.
