What Is Ductless Heat Pump?

People nowadays are very much concerned about maintaining comfort at home in all seasons and ductless heat pump is found to be one of the most popular solutions available.

Let us try to understand what is a ductless heat pump?

Ductless heat pump which is also popularly known as mini-split air conditioner does not depend upon any ducting system to transfer heat within the room.

Also, in addition, ductless heat pumps will provide air-conditioning by just reversing the flow of refrigerant between indoor and outdoor units.

How these ductless heat pumps work?

Basically, ductless heat pump will work by moving warm air from one particular location to another location. Generally, it consists of the following two units.

  1. One outdoor compressor unit
  2. Indoor air-handling units.

Such systems can either be single-zone system or multi-zone systems which will be depending upon a number of units. For any small homes a single-zone system can be ideal. Whereas for larger buildings multi-zone systems will be needed.

Heat is transferred in these ductless heat pump systems, through an evaporation and condensation cycle. Refrigerant substance will cycle through the system by using a compressor pump.

There are 2 heat exchanger coils in these ductless heat pump systems and one condenses the refrigerant while another evaporates it. Refrigerant will absorb heat from surrounding areas during evaporation process.

During condensing process, heat is released that was previously absorbed. These ductless heat pumps will maintain desired temperature which is set by thermostat.

What are the advantages of heat pumps over HVAC systems?

Following are the advantages of such ductless heat pumps in comparison with the traditional HVAC systems.

  • Lower operating costs

Since these heat pumps are quite energy efficient, the operating cost to run them will be much economical as compared to traditional HVAC system.

  • Easy to install

As compared to earlier HVAC system, it is much easier to install this kind of heat pump system.  A 3” hole is needed on the wall in order to make interconnection between indoor/outdoor units.

  • No ducts necessary

No ducts will be needed to circulate the hot or cool air inside the room. Usually such duct systems are prone to leaking which may reduce 30 per cent of cool air.

  • Flexibility

These units are not too heavy to carry and can be easily installed at your homes without much difficulty.

  • Can be controlled by using remote control

These systems also include remote control which is useful to make adjustment in temperature and air speed etc.
