Eco-Friendly Inverter Controller Boards for Air Conditioners

The global air conditioning systems market size was USD 102.02 billion in 2018 and is expected to register a CAGR of 9.9% from 2019 to 2025. The rising number of auditoriums, hospitals, hotels, and multiplexes across the globe is anticipated to accelerate the market growth for air conditioning in the near future. Also, the increasing disposable incomes of individuals are expected to encourage the uptake of a variety of air conditioning systems. Rising inclination of consumers towards energy-efficient systems and the growing popularity of portable systems is expected to positively impact the air conditioning systems market growth as well.

While most of the world craves indoor comfort at economical costs, eco-friendly inverter air conditioners are garnering special attention in India, where recently-enacted energy efficiency regulations mandate the future construction of green buildings, with significantly lower power and water consumption, while the climate of India requires additional topicalization of compressors and other AC components against extreme heat and humidity. Most of India’s summer is very hot. It begins in April and continues until the beginning of October, when the monsoon rains start to fall. The heat peaks in June with temperatures reaching up to 45°C (113°F) or higher. [2]

In 2019, Energy Efficiency Services Limited (EESL), a joint venture of four Public Sector Enterprises under the administrative control of the Ministry of Power, Government of India, announced the launch of Super-Efficient Air Conditioning (SEAC) program. The program is aimed at promoting the use of energy-efficient technologies and bring about a reduction in energy consumption. Through this program, the Ministry of Power in India also aims to address India’s Hydrochlorofluorocarbons Phase-Out Management Plan and Cooling Action Plan by 2032. [3]

Syrma’s AC Inverter Controller Boards

A few years ago, India’s leading home and commercial appliance brand approached us with design challenges for an energy-efficient power inverter, a vital component of air conditioners which essentially re-converts DC current back into AC, necessary to modulate compressors and other internal induction motors. We created a new design team specifically for this project, collaborating with the client to successfully co-develop the new inverter. We were also contacted by a major European maker of residential and commercial HVACR systems with a similar opportunity. Our initial foray into inverters led us to realize there’s a rapidly growing need among the world’s HVACR OEMs for redesigned, energy-efficient power components at reasonable costs.

We offer two variants of inverter controller boards: a high-frequency controller for maximized energy efficiency, and a low-frequency controller, designed for optimized cost competitiveness and to provide better efficiency throughout the temperature range. Circuit-board microcontrollers enable the inverter to automatically regulate the volume of the BLDC compressor motor, compensating for fluctuating climate conditions, the highest speeds in extremely hot weather to lower speeds in cooler temperatures, reducing normal power consumption by 30-50%. This board decreases operating noise by using four different temperature sensors to quietly ramp up/down compressor motor speed. It also limits daily wear and extends service life by more than 5 years.

This board is universally adaptable to any model of any manufacturer’s air conditioner and it can drive various types of compressors available in the market including BLDC and IPM types. It’s based on the latest technology using a wide-efficiency range and it can be optimized for customized solutions. Our inverter uses a proprietary control algorithm that runs on an efficient digital signal controller. The power factor correction topology uses a smaller number of components and the intelligent power module integrates gate drive control, power supplies, and inverter switches into a single chip. The remote controller is part of the indoor unit controller, which communicates with the outdoor unit controller via power line communication.

Backed by 40 Years of Expertise

Syrma Technology contributes 40 years of design and manufacturing expertise spanning multiple diverse markets, and we look forward to discussing how we can deliver world-class products for OEMs across the globe. We understand our home India market, familiar with its vast regulatory and selling environments. We foster growth opportunities within India through our strong technology incubation ecosystem. We also assist global companies seeking to enter the Indian market by leveraging the local supply chain and favorable operating environments for cost reductions.

Over the years, we’ve manufactured several different kinds of boards that are used for gas detectors. These detectors are mainly used for industrial HVAC control systems. Besides facilitating ventilation control, they monitor controlled combustion in industrial furnaces and measure oxygen levels in confined spaces, which improves indoor air quality. Working as an OEM partner, we’ve developed these boards for several Fortune 500s, as well as for large companies based in Europe and India.
