LG Dual Inverter Smart Air Conditioning Review: This Wi-Fi connected window air conditioner is a big step up



There are millions of old-fashioned window air conditioners out there, but the technology for the ugly, noisy boxes has not changed much. You can do smarter by connecting it to a third-party controller such as Sensibo Sky, Ambi Climate 2 or Tado Smart A / C Remote, and that can reduce energy consumption; But if yours is on the last legs, you better retire it and buy something new that has a built-in brain. That's what LG's Dual Inverter line of connected window air conditioners have, and they're extremely efficient to boot.

LG's Dual Inverter line ranges from a 9,500 BTU unit to a 22,000 BTU sample that relies on a 220-volt outlet (an electric dryer will use). I reviewed LG's model LW1

517IVSM, which connects to a more common 15-amp, 120-volt grounded outlet and is rated at 14,000 BTU. BTU, by the way, is an acronym for the British Thermal Unit. When used in conjunction with air conditioners, it measures the amount of heat that the air conditioner can remove from a room. So the higher the BTU figure, the more powerful the air conditioner.

Manufacturers can also specify the square footage that an A / C unit should be able to cool. LG recommends this unit for rooms up to 800 square meters. I tested it on a 600 square foot loft that was converted into bedrooms. The remodeling did not bring channels from the central HVAC system to this room, so the space gets incredibly hot in the summer. A window air conditioner is a must.

What is a converter?

Before discussing this air conditioning's smart features, let's talk about the underlying technology that makes it more efficient than most. An air-conditioning compressor motor circulates the refrigerant used for heat exchange. On the typical air conditioner, the compressor motor operates at a fixed speed regardless of the ambient temperature and the target temperature you set with the air conditioner controls. The compressor is fired and works with full tilt until the measuring temp is reached. It then turns off and waits for the ambient temperature to rise above the target again, at which point it starts up again. This cycle is repeated over and over until there is no longer any need for air conditioning.

Controlling the LG Dual Inverter air conditioning's basic operations with the SmartThinQ app is decent enough. [19659009] An air conditioner like this one from LG avoids the temperature control on the roller coaster because it is driven by a variable speed compressor motor. It can start firing the compressor at full speed at first, but when the target temperature is reached, the lowering compressor motor to will maintain that temperature, instead of turning it off and waiting for the room to get too hot . Essentially, the air conditioner determines how hard it needs to work to maintain the desired temperature, and it instructs the compressor engine to function accordingly.

As a result, LG states that Dual Inverter air conditioners are up to 25 percent more efficient than what is required to obtain the US Government's EnergyStar certification. For example, the EnergyGuide label on the model LW1517IVSM reviewed here estimates that it will cost a consumer $ 68 to operate this device for one year, compared to a range of $ 115 to $ 182 for similar less efficient models.

This approach also provides another benefit: Since the compressor motor in an inverter air conditioner is not constantly running at full capacity, this type of equipment does not produce as much noise. This LG unit was absolutely silent – the whispered wasn't quiet, but it was less noisy than any other window air conditioner I've heard.

Easy Installation

But no self-respecting smart home dweller will fiddle with buttons on a control panel when they can give voice commands to a smart speaker or use a smartphone app. This is where the air conditioning Wi-Fi adapter on board (alas, it will only connect to 2.4 GHz networks) and LG's SmartThinQ app come into play. The device is also compatible with both Amazon Alexa and Google Assistant.

The SmartThinQ app does a great job of controlling and adjusting the air conditioner from afar, but you will get significant errors when drilling into the planning options. The app lets you schedule days and times when the air conditioner will turn on and off, but you can't create schedules with target temperatures throughout the day. There's also home, away and vacation mode in the SmartThinQ app, but they're incredibly blunt about what they do and how they can be adjusted.

The problem stems from the fact that SmartThinQ is designed to control a range of LG smart appliances – refrigerators, washers and dryers, robotic vacuum cleaners and even LG TVs – so many of the options in it don't apply in that all A / C units.
