Smart defrost in heat pumps refers to an intelligent and automated defrosting process designed to enhance the system’s efficiency during cold weather. Heat pumps can accumulate frost or ice on their outdoor coils, hindering performance. Smart defrost systems monitor various factors, such as temperature and humidity, and initiate defrost cycles when necessary. By optimizing the timing and duration of defrosting, smart defrost technology minimizes energy consumption, ensuring the heat pump operates at peak efficiency even in cold conditions. This feature contributes to improved overall performance and energy savings in heat pump systems.

The energy class of heat pumps can vary depending on the specific model and its energy efficiency rating. Heat pumps are typically rated on a scale from A+++ to D, with A+++ being the most energy-efficient and D being the least. The rating is based on the Coefficient of Performance (COP), which measures the efficiency of the heat pump in converting energy to heat. Higher COP values result in a higher energy efficiency rating and a better energy class.

SOL AIRPOWER heat pumps have the highest level of energy efficiency: A+++.

At the core of the Solplanet SOL AIRPOWER heat pump system lies a Panasonic compressor equipped with EVI technology. This device operates at variable rotational speed, adapting to the prevailing energy demand. The implementation of DC inverter sine wave control has resulted in remarkable efficiency across a broad operational range, maintaining a low noise level for optimal user comfort. This advanced technology ensures the system operates efficiently and quietly, delivering a superior level of comfort in its use.

EVI stands for Enhanced Vapor Injection and it is a technology that enhances the efficiency and performance of the heat pump, especially in colder climates.

In a heat pump, the refrigerant plays a crucial role in transferring heat. EVI technology involves injecting additional vapour into the compressor to increase its capacity and efficiency, allowing the heat pump to maintain satisfactory performance even at lower outdoor temperatures. This makes EVI-equipped heat pumps well-suited for heating applications in regions with colder climates, as they can extract heat from the air or ground more effectively in suboptimal conditions. The technology contributes to improved heating capacity and efficiency of up to 30%.
