How EVI Technology Keeps Your Home Warm in Freezing Winters?

When the icy grip tightens during winter, standard heat pumps are unable to deliver consistent warmth that can leave homeowners shivering and energy bills soaring. How about installing a DC Inverter Heat Pump with Enhanced Vapor Injection (EVI) technology?

By boosting performance by 27-30% in freezing temperatures, the inverter heat pump ensures that your home stays comfortable and efficient, regardless of how harsh the winter is. Please check out this post and know how this innovative system works and why it’s the ideal choice for battling harsh cold weather:

 

What Do You Mean by EVI Technology?

Enhanced Vapor Injection (EVI) is a highly advanced technology designed to maximize heat pump performance in low temperatures. Unlike traditional heat pumps that lose efficiency as the mercury drops, EVI-equipped systems, like DC Inverter Heat Pump, use a refrigeration cycle to deliver more heat, even in sub-zero conditions. This is because of a compact internal plate heat exchanger called an “economizer” and a clever bypass valve system that supercharges the compressor’s output.

How EVI Works to Beat the Cold?

The magic of EVI happens within the heat pump’s refrigeration cycle. Please check out its simplified breakdown:

1. Economizer in Action – The heat pump system uses a 33% smaller internal plate heat exchanger, known as the economizer, to boost efficiency. This component allows the heat pump to extract more heat from the outside air, even when temperatures go below. 
2. Vapor Injection Boost - A bypass valve redirects some of the hot refrigerant vapor from the condenser to the economizer. This vapor combines with colder gas from the evaporator side and increases gas temperature further.
3. Compressor Power-Up - The warmed gas is injected into the head of the scroll compressor with a dedicated vapor injection port at mid-range pressure. This process increases the compressor’s ability to produce heat and overcome the limitations of standard heat pumps in cold weather.

This results in a heat pump that delivers higher flow temperatures and a superior Coefficient of Performance (COP), which ensures more heat output with less energy input.

Why EVI Works in Harsh Winters?

Standard heat pumps often find it difficult to work in freezing conditions as they struggle to extract enough heat from cold air. This ensures much longer run times, higher energy costs, and cold homes. 

EVI technology, however, boosts efficiency by 27-30% and allows the DC Inverter Heat Pump to maintain its performance even in extreme cold. Homeowners living in areas with harsh winters can rely on consistent warmth without cranking up the thermostat or worrying about increasing bills.

Additional Benefits of EVI Heat Pumps

Apart from cold-weather prowess, EVI technology combines perfectly with the variable-speed Panasonic EVI compressor in our DC Inverter Heat Pump. This dynamic duo ensures accurate temperature control, faster heating, and reduced wear on components, which can extend the system’s lifespan. In addition, the energy savings translate to a lower carbon footprint and make EVI heat pumps an eco-friendly choice for sustainable living.
