Explore our state-of-the-art residential and high-temperature air source heat pumps designed for high-efficiency operation under extreme cold climates.
Decarbonization is no longer just a regulatory compliance check; it is a profound transformation of global industrial and municipal utility architectures. Traditional boilers, which burn natural gas, coal, or diesel, are responsible for a significant fraction of direct Scope 1 emissions globally. Transitioning these systems to electric options presents a structural engineering challenge: how to deliver high discharge water temperatures (ranging from 65°C up to 90°C) without compromising the Coefficient of Performance (COP) or suffering catastrophic failures in sub-zero climates.
As a premier China high temperature heat pump supplier, our manufacturing practices and research programs focus directly on addressing this dynamic. Across Europe, North America, and Northeast Asia, the phaseout of fossil fuels has elevated heat pumps to standard specifications for new builds and extensive retrofits. Major trends driving the deployment of these technologies include:
Professional procurement leads look beyond marketing copy. The following matrix details the critical parameters engineers and HVAC contractors prioritize when evaluating suppliers.
Buyers look for ERP A+++ certification values at both 35°C and 55°C. High temperature air-to-water units must demonstrate robust SCOPs above 3.5 in moderate zones to offset energy bills against gas boilers.
At low ambient temperatures (-25°C to -30°C), air-to-water efficiency drops. EVI compressors inject superheated refrigerant vapor directly into the compression cycle, keeping discharge high and maintaining stability.
To reach 80°C or 90°C, cascade cycles (R134a/R410a, R290/CO2) are employed. This enables low-pressure-ratio operating configurations that prolong the operational life of scroll and screw compressors.
