Description

Air source heat pump hot water KDR05

Air energy heat pump technology is loved by consumers for its advantages of environmental protection, energy conservation, safety, and comfort.

Features:

1. Energy saving and high efficiency

Advanced air jet enthalpy increasing system, high-efficiency heat exchanger technology, high-efficiency fan motor, optimized hood design, and other technologies are adopted, which can make the average refrigeration energy efficiency ratio of the heat pump unit reach 3.58, the average heating energy efficiency ratio reaches 4.32, and the average cooling and heating energy efficiency ratio reach 3.95, greatly reducing the refrigeration and heating operation cost of the air energy heat pump.

2. Performance improvement in severe cold

The low ambient temperature heat pump realizes heating operation within – 25 ℃ ~ 43 ℃. Through air jet enthalpy increasing, the heating capacity of the compressor under severe cold is increased, and the heating capacity under – 15 ℃ is increased by nearly 20% – 50%, leading the air energy heat pump into the era of “strong cold and heat”. When the outdoor temperature is very low, the heat exchange capacity of the outdoor unit decreases, the return air volume at the normal return port of the compressor decreases, and the compressor power decreases, which cannot play the best effect.

The refrigeration gas is supplemented through the intermediate pressure return gas injection port, so as to increase the exhaust capacity of the compressor, increase the circulating refrigeration dose of the indoor unit heat exchanger, and increase the heating capacity.

Therefore, it is more suitable for cold areas.
