What does a mini split AC do?<\/b><\/h2>\n

Mini split ACs allow the user to control the temperature in a single room or space. Since it\u2019s a type of heating or cooling system that removes or adds heat through a typical refrigeration or heating process for a designated space, it doesn\u2019t need any ductwork. Mini split ACs are also referred to as ductless units for this reason.<\/span><\/p>\n

To switch between cool and heat, you just toggle the desired mode. There are other modes offered on some MRCOOL units such as fan-only and dehumidification.<\/span><\/p>\n

Key parts<\/b><\/h2>\n

A MRCOOL mini split AC system consists of three main parts: the compressor or condenser unit, the indoor air-handling unit (also referred to as the evaporator or air handler), and the conduit that connects them. Let’s take a closer look at each component and its role in the overall system.<\/span><\/p>\n

Indoor air-handling unit<\/b><\/h3>\n

The indoor air-handling unit, which is often mounted on a wall or ceiling, is where the magic happens. This unit contains the evaporator coil, which absorbs heat from the indoor air. As the refrigerant passes through the evaporator coil, it absorbs heat from the surrounding air, which causes it to cool and dehumidify the space.<\/span><\/p>\n

Condensing unit\u00a0\u00a0<\/b><\/h3>\n

The condensing unit is the beating heart of the mini split AC system. This outdoor unit houses the compressor, condenser, and condenser fan. The compressor circulates refrigerant through the system. The condenser condenses the refrigerant, where it gives off the heat absorbed in the evaporator.\u00a0<\/span><\/p>\n

Line set\u00a0\u00a0<\/b><\/h3>\n

The line set is a set of insulated pipes that connect the indoor and outdoor units. It consists of a smaller copper pipe (the liquid line) and a larger copper pipe (the suction line). These pipes allow the refrigerant to flow between the two units and help transfer heat in the cooling or heating process.<\/span><\/p>\n

How does the MRCOOL cooling process work?<\/b><\/h2>\n
    \n
  1. The refrigerant, in a low-pressure liquid state, enters the indoor air-handling unit’s evaporator coil.\u00a0<\/span><\/li>\n
  2. As the refrigerant passes through the coil, it absorbs heat from the indoor air, which causes it to evaporate into a gaseous state.<\/span><\/li>\n
  3. The gaseous refrigerant is drawn into the compressor in the outdoor unit, where it\u2019s compressed. This compression process raises the temperature and pressure of the refrigerant gas.<\/span><\/li>\n
  4. The hot, high-pressure refrigerant gas enters the condenser coil of the outdoor unit, where it releases the absorbed heat from the indoor space to the outside air. This heat rejection causes the refrigerant to condense back into a liquid state.<\/span><\/li>\n
  5. The liquid refrigerant passes through an expansion valve, which causes a sudden drop in pressure and temperature.\u00a0<\/span><\/li>\n
  6. The cooled, low-pressure liquid refrigerant returns to the indoor air-handling unit, where the cycle repeats.<\/span><\/li>\n<\/ol>\n

    This continuous cycle of heat absorption, compression, condensation (heat rejection), and expansion keeps the space cool while the heat is transferred outside.<\/span><\/p>\n

    The heating process for heat pump units is the cooling process in reverse. Units with strip heat have an electric heating element added to the indoor unit.<\/span><\/p>\n

    Advantages of a MRCOOL mini split AC system<\/b><\/h2>\n

    Energy efficiency<\/b><\/h3>\n

    These systems are designed to deliver superior cooling and heating performance while consuming less energy compared to traditional HVAC systems. The advanced inverter technology used in MRCOOL units allows for precise temperature control, a reduction in energy consumption and potentially lower utility bills.<\/span><\/p>\n

    Targeted cooling and heating<\/b><\/h3>\n

    Unlike traditional central air conditioning systems, MRCOOL mini split AC systems offer zoned cooling and heating. Each indoor air-handling unit can be controlled independently so you can cool or heat specific areas or rooms as needed. This feature can bring comfort to your home and contribute to energy savings by only cooling or heating occupied spaces.<\/span><\/p>\n

    Flexible installation<\/b><\/h3>\n

    The MRCOOL mini split AC systems are also flexible for installation. Since they have a compact design, they can be installed in several different locations including walls, ceilings, and even drop ceilings. These units tend to be an excellent choice for spaces with limited ductwork or specific cooling and heating requirements.<\/span><\/p>\n

    Quiet operation<\/b><\/h3>\n

    MRCOOL mini split AC systems are known for their quiet operation due to their advanced compressor technology and sound-dampening design features. The indoor air-handling units operate at a whisper-quiet level to keep a peaceful indoor environment.<\/span><\/p>\n

    Improved indoor air quality<\/b><\/h3>\n

    Many MRCOOL mini split AC systems come equipped with advanced air filtration systems that help remove airborne particles, allergens, and pollutants from the indoor air. This feature can help you maintain a healthier indoor environment and prevent dust and debris buildup in the machine.<\/span><\/p>\n
