Product Detail

Product Tags

SolarShine’s low ambient temperature air source heat pump adopts the ultra-low temperature compressor and low- temperature, and environment- friendly refrigeration 410, which is widely used in cold areas in Europe. The heating efficiency at low temperature (- 25 ℃) is 50% - 80% higher than that of conventional air source heat pump units. The air source heat pump unit has little heating attenuation when the ambient temperature drops sharply, which fully ensures the heating effect.

It is generally used for floor heating and hot water production in cold areas in winter such by EU market. Its energy-saving effect is obvious, which is about 1/ 3 of the cost of other heating equipment. It is the primary choice for commercial places’ water heating, floor heating and refrigeration, and for domestic hot water supply such as families, communities, hotels, and villas.

SolarShine’s comprehensive energy- saving solution is recommended for the areas where the minimum temperature is lower than- 5C. The heat pump system operates as follow:

Summer: priority to start the hot water mode to meet the demand for hot water.

Winter: the system operates in the hot water heating mode first to meet the hot water demand. When the hot water temperature reaches the set temperature, the system automatically switches to the heating operation mode to realize floor heating.

The system also can be designed to heat or cool the house, with components of heat pump, circulation pump, buffer tank, manifoil for heating and cooling.
