Split Air Conditioners

Split air conditioners are a type of air conditioning system consisting of an indoor unit and an outdoor unit. The indoor unit cools the air, while the outdoor unit is equipped with a compressor and other components. The demand for split air conditioners in India is on the rise due to rising temperatures, soaring disposable income, and a growing middle class. A report by Research andMarkets shows that the AC market will grow at a CAGR of 13.7% between 2020-2025, with split air conditioners topping the sales chart. This growth is attributed to increasing urbanization, rising temperatures, and the availability of energy-efficient models. The makers of Split Air conditioners must have BIS certification to legally Air Conditioners. Read on to find out how to secure BIS certification for Split Air Conditioners.

An Outlook of IS 1391(Part 2):2018 – An Indian Standard for Split AC

IS 1391(Part 2):2018 covers split air conditioners. This standard specifies the design and performance norms for split air conditioners. This standard also pens down the test circumstances and procedures for various performance factors of these air conditioners that run frost-free when cooling and dehumidifying at standard rating conditions.

This standard specifies split air conditioners that can work as heaters by leveraging a heat pump or an electric heater. It comprises two parts: an inside unit and an outdoor unit.

The indoor unit can be installed on the wall, floor, or ceiling. The compressor, heat exchangers, fan motors, & air handling system are equipped in two separate cabinets in the Indoor and Outdoor units.

These ACs are intended to supply conditioned air to an enclosed space. It has a primary source of refrigeration for cooling & dehumidification & mechanisms for air movement & filtering. The manufacturer must ensure that the product adheres to the standard’s general, construction, & performance norms.

Split air conditioners are classified as shown below based on their function and nominal cooling capacity.

  • Classification by Function
  • Cooling and Dehumidification
  • Cooling and Heating by Heat Pump
  • Cooling and Heating by Electric Heater
  • Unit Type
  • Single Split having Single Indoor & Outdoor Unit
  • Unit Mounting Arrangement
  • Floor Type
  • Multi Split having Multiple Indoor & Single Outdoor Unit
  • Ceiling Type
  • Wall Type

The nominal cooling capacity of split ACs should be classified as follows:

3000, 4500, 6000, 7500, & 9000 kcal/h.

The air conditioner & its components must be built with apt strength and rigidity to counter regular handling, transit, & operation conditions. They should be free from sharp edges or comers that could cause human injury.

Materials used in the construction of cabinets, front panels, & so on must adhere to corresponding Indian Standards wherever applicable unless modified by this standard. The manufacturer must assure the soundness of the construction and the AC’s performance.
