Ductless mini-split systems are gaining popularity because they’re energy-efficient, flexible, and easy to install. Whether you’re thinking about getting one for your home or just curious about how they work, it’s helpful to know what makes up these systems.
In this blog, we’ll examine the main parts of a ductless mini-split system and how they work together to keep your home comfortable.
1. Outdoor Unit
The outdoor unit is the central hub of the ductless mini-split system, often called the condenser or compressor. It’s usually installed outside your home and is responsible for transferring heat with the outside air. Here’s what’s inside:
- Compressor: This part pumps refrigerant through the system, turning it into a high-pressure gas that moves to the condenser coil.
- Condenser Coil: This coil releases the heat it absorbs from inside your home into the outside air.
- Fan: The fan helps eliminate the heat released by the condenser coil.
2. Indoor Unit
The indoor unit, or evaporator, delivers the heated or cooled air into your living space. You usually see these mounted on a wall, but they can also be ceiling-mounted or floor-mounted. Inside the indoor unit, you’ll find:
- Evaporator Coil: This coil absorbs heat from your indoor air, cooling it as the refrigerant evaporates inside the coil.
- Air Filter: This filter traps dust, allergens, and other particles to keep your indoor air clean.
- Blower: The blower moves the cooled or heated air from the evaporator coil into your room.
3. Refrigerant Lines
Refrigerant lines, or line sets, are insulated copper pipes connecting the indoor and outdoor units. These pipes carry the refrigerant back and forth, making the heat exchange process happen. There are two main types:
- Suction Line: Carries low-pressure refrigerant vapor from the indoor unit back to the outdoor unit.
- Liquid Line: Carries high-pressure liquid refrigerant from the outdoor unit to the indoor unit.
4. Electrical Wiring
The electrical wiring connects the indoor and outdoor units, allowing them to work together. This wiring usually includes:
- Power Supply Cable: Provides electricity to the outdoor unit.
- Control Wire: Sends signals between the indoor and outdoor units.
- Communication Wire: Lets the thermostat or remote control adjust settings and monitor performance.
5. Condensate Drain Line
The condensate drain line removes the moisture that forms when the system cools the air. When warm air passes over the cold evaporator coil, condensation happens, and this line helps drain it away to prevent water damage and mold.
- Drain Line: Carries the condensed water from the indoor unit to a drain outside your home.
6. Thermostat or Remote Control
This is what you use to adjust the temperature and settings of your ductless mini-split system. Modern systems often have advanced features like programmable settings, Wi-Fi connectivity, and smartphone apps.
- Thermostat: A wall-mounted device that offers precise temperature control.
- Remote Control: A handheld device that lets you adjust settings from anywhere in the room.
