Mini Split Without Condenser: A Comprehensive Guide

A mini-split air conditioning system typically consists of two main components: an indoor air handling unit and an outdoor condenser unit. However, there are condenserless mini-split systems available that do not require an outdoor unit. These systems, also known as “through-the-wall” or “monoblock” units, work by drawing air into the unit and passing it over coils, similar to a standard air conditioning system, but without the need for an outdoor condenser unit.

Understanding Condenserless Mini-Split Systems

Condenserless mini-split systems work by using ducts to draw air from the outside and pass it over the coils to release the heat, instead of using an outdoor condenser unit. This design allows for easier installation, as there is no need to install an outdoor unit.

One example of a condenserless mini-split system is the 2.0 H2O 12 HP DC Inverter from Monoblock, which is available on Archiproducts. This unit is a monoblock air conditioner without an external unit, and it features a heat pump for both cooling and heating.

Advantages and Disadvantages of Condenserless Mini-Split Systems

Advantages:

  • Easier installation process as there is no need for an outdoor unit
  • Can be a more cost-effective option for those who only need to cool a small space
  • Can be a good option for those looking for a more temporary solution, as they can be easily removed and reinstalled

Disadvantages:

  • May not be as effective as traditional mini-split systems with an outdoor condenser unit
  • May not be able to cool large spaces efficiently
  • May cost more in electricity bills due to the lack of a condenser
  • May not be as durable as traditional mini-split systems and may require more frequent maintenance

Installation Considerations

Condenserless mini-split systems are generally easier to install than traditional mini-split systems, as they do not require any outdoor installation. They can be installed against an outside-facing wall with the supplied grilles and a condensate drainpipe. However, it’s still recommended to have a professional install the unit to ensure proper installation and to avoid any potential issues.

Technical Specifications and Measurements

The 2.0 H2O 12 HP DC Inverter from Monoblock is a condenserless mini-split system with the following specifications:
– Cooling capacity: 12,000 BTU/h
– Heating capacity: 14,000 BTU/h
– Energy Efficiency Ratio (EER): 3.3

According to D-Air, condenserless mini-split systems may not be as effective as traditional mini-split systems, and they may cost more in electricity bills due to the lack of a condenser.

Maintenance and Durability

Condenserless mini-split systems may require more frequent maintenance and may not be as durable as traditional mini-split systems. They are more prone to overheating and may require more frequent cleaning of the coils and filters.

Conclusion

Condenserless mini-split systems offer a unique solution for those who do not have the space or desire for an outdoor condenser unit. While they may not be as effective or durable as traditional mini-split systems, they can be a more cost-effective and straightforward option for those who only need to cool a small space. It’s important to weigh the pros and cons and consider the specific needs of your space before deciding on a mini-split system.
