EVI stands for “Enhanced Vapor Injection” and is a technology used on our cold climate heat pumps to achieve higher performance at lower temperatures. An EVI heat pump uses a 3rd smaller internal plate heat exchanger called an “Economizer” within the refrigeration cycle.
Using EVI heat pump technology, we are able to overcome the limitation of maximum flow temperature that other cold climate heat exchangers encounter. EVI Heat Pump technology allows more heat to be delivered resulting in a better COP at much lower temperatures. The EVI technology increase performance efficiency by 27-30%.
Wide operating temperature range. even in cold climate ranging from -20→ to 45→, and can work safely and reliably at ambient temperature as low as -30→ with Wet Injection.
R32 is a next generation refrigerant that has efficient performance and lower environmental impact. R32 is known as difluoromethane and belongs to the HFC family of refrigerant. Its chemical formula is CH2F2.
R32 has lower GWP (Global Warming Potential). As an illustration the GWP of R32 is 675 compared to R410A (GWP 2088); R407C (GWP 1774); R134A (GWP 1430).
R32 has similar working pressures as R410a but delivers slightly more capacity. It works 10% higher efficiency than R22, and at least 5% higher efficiency than existing R410A.
Besides, R32 is a single component refrigerant, meaning it is easier to reuse and recycle. It is also relatively inexpensive to produce, and easier to handle.
Air conditioners maintain set temperature by cooling when room temperature rises above the set temperature and heating when the room temperature falls below the set temperature. Motor speed in non-inverter type air conditioners remains constant and temperature is adjusted by turning the motor ON and OFF, which consumes more energy. In inverter type air conditioners, temperature is adjusted by changing motor speed without turning the motor ON and OFF.
The below chart shows how conventional non-inverter type and inverter type works. Compared to non-inverter type air conditioners, air conditioners with inverters have less power loss and can save in energy.
1.) Lower operating costs
Since inverter motors will only use as much energy as they need for your desired temperature settings, you can expect to see huge savings on your energy bills when you switch to an inverter-based air conditioner. You can save up to 58% on your energy consumption, compared to when you use a traditional air conditioner. Considering that air conditioners tend to be the most power-hungry appliances in most households, these savings may very well cover your initial investment in just a few years.
2.) Faster start up time
An inverter AC will generally reach a desired thermostat temperature faster than a non-inverter equivalent. An inverter will be able to use much more power for the initial phase, then progressively diminish it as it gets close to the needed temperature. This will be much slower for a non-inverter AC, as their motors’ stop-start cycles necessitate a less precise operation. They will tend to make the room colder than the target temperature for a short time before shutting down, restarting when the room becomes warmer than the target temperature.
3.) Quieter operation
If you’re used to the noise of a regular air conditioner in your home or office, the reduced noise of an inverter air conditioning unit can be a pleasant surprise. Many users report that they sometimes forget the unit is there. As the motor only works as hard as it needs to, there is less of a need to keep it running at full capacity, thereby reducing the amount of running noise.
Regular air conditioners also have a characteristic thud when they start up and when they reach the desired thermostat temperature, an unavoidable consequence of having a static motor speed. An inverter unit’s compressor motor can speed up and slow down much more smoothly.
4.) Better comfort
The biggest reason to getting an inverter boils down to user comfort. The quieter operation and precise temperature control make them perfect for getting a good night’s sleep and preventing untimely distractions in the office. The enormous energy savings and the reduced impact on the environment can also quell some of the guilt and mental stress many of us have over running what was traditionally a very power-hungry appliance.
