Product Features
Efficient and energy-saving
The EVI technology of low-temperature air source heat pumps significantly improves the heating capacity at low temperatures. The optimized design of various components for IPLV, higher energy efficiency ratio, and intelligent defrosting technology overcome the shortcomings of traditional air-cooled heat pumps that cannot improve the heat source at low temperatures. The efficiency of using air capacity for heating fills the gap in cold regions where heat pumps can be used for heating, without the need for auxiliary electric heating;
Wider heating operation range
Overcoming the limitation that ordinary air-cooled heat pumps cannot operate normally at temperatures below -10 ℃, they can still provide strong heating at temperatures of -25 ℃, with a water outlet temperature of up to 60 ℃ (which can be achieved by combining the air-cooled unit with the water source heat pump to achieve a water outlet temperature of 75 ℃). They are suitable for areas between 38 ° -43 ° north latitude as heating sources in winter and cooling sources for air conditioning in summer, with a combination of cold and heat sources, saving equipment investment and low operating costs;
Green, environmentally friendly, and pollution-free
Adopting clean and green energy - electricity, the system avoids environmental pollution caused by mineral fuels. During the hot water production process, there is no pollution of dust suspended particles, waste residue, wastewater generation, and emissions of sulfides, heliides, carbon monoxide, and carbon dioxide. It is an environmentally friendly and pollution-free green product;
Innovate traditional heating methods
The centralized heating system in the north has shortcomings such as low efficiency and high consumption, environmental pollution, fixed heating cycles, multiple operation and maintenance problems, and difficult fee management, which cannot meet the requirements for building energy conservation. The ultra-low temperature air-cooled heat pump can provide cooling and heating at any time according to customer needs, adjust the output capacity, and freely adjust indoor temperature. At the same time, it integrates refrigeration and heating, reducing installation and maintenance costs;
Compressor characteristics
Can be used in parallel to meet high cooling demand;
The evaporation temperature can be as low as -60 ℃;
The dual stage compressor has a simple structure and principle, which can significantly reduce control costs;
Strong liquid compression resistance, low noise, low vibration, and no need to install shock absorbers;
-When applied at low temperatures ranging from 30 ℃ to -60 ℃, the efficiency of the single stage low-temperature screw compressor is more than 30% higher, and the cost-effectiveness advantage is obvious;
Inherit all the original advantages of the module unit
Modular combination, segmented start, multi-level adjustment, energy-saving and comfortable, excellent performance, and investment saving; Short construction period, convenient installation, intelligent defrosting, unique
1. Low temperature air source heat pumps exchange heat in the air for cooling/heating, achieving the purpose of refrigeration/heating;
2. Exchange a small amount of electrical energy for a larger amount of air thermal energy;
3. Low temperature air source heat pumps replace low-level heat with high-level heat through air heat exchange, thereby achieving the effect of heating buildings in winter;
4. Low temperature air source heat pumps are mainly composed of finned evaporators, compressors, condensers, expansion valves, and other main components. They evaporate refrigerant in the evaporator, absorb heat from the outdoor environment, and then increase temperature and pressure through the compressor. The refrigerant then enters the condenser to release heat energy, which is converted into hot water in the condenser and transported to the indoor radiator equipment for heating, The refrigerant is throttled and depressurized (expansion valve) before entering the evaporator, forming a thermal cycle process that transfers solar energy and the heat from the external low-temperature environment to water for heating and sanitary hot water use. The low usage environment temperature is -25 ℃, and the energy efficiency ratio is 1:3 when the winter environment temperature is 0 ℃, which is 1/3 of the point heating electricity consumption and 2/3 of energy saving;
