About Refrigerants
Background: Global Warming Potential (GWP) and Ozone Depletion Potential (ODP) are important indicators for evaluating the environmental friendliness of refrigerants. Choosing refrigerants with low GWP and zero ODP can help reduce adverse impacts on the atmospheric layer.

Yijiaren can use refrigerants R410A, R290, R32, and R134A, each with different refrigeration capabilities and efficiencies. We can select the appropriate refrigerant according to specific refrigeration needs.

*Low-temperature air-source hot water unit uses air as a heat exchange medium to generate hot water.
*Adaptability to low environmental temperatures: Utilizing enhanced enthalpy technology, it can reliably operate at -25 degrees Celsius without requiring auxiliary electric heating.
*High low-temperature heating performance: COP (Coefficient of Performance) for heating at -25 degrees Celsius reaches 2.052. *Addresses the reliability and low efficiency issues of traditional air-source heat pump units in low-temperature heating. Particularly suitable for the Yellow River Basin, North China (including Beijing), and Northwest China. Greatly expands the application scope of air-cooled heat pumps.
*Compact unit structure, small footprint, eliminating the need for refrigeration rooms and cooling towers, saving space while effectively controlling investment costs.

Working principle

Product configuration
1. High Energy Efficiency Heat Pump Low Temperature Compressor

Using famous brand ZW series scroll compressors, mature and reliable technology, high production level. Yijia air energy water heater's second-generation products are greatly improved in performance, especially in heating capacity and long service life through system optimization design and the application of various parts.

2. Multi-flow Evaporator

Using internally threaded copper casing hydrophilic aluminum foil multi-path evaporator, blue hydrophilic film aluminum foil fins combined with internally threaded copper pipes, the surface has hydrophilicity, using the rapid discharge of condensation water, not easy to frost, defrost thoroughly, In order to ensure the durability of the system, the effective heat exchange area of the evaporator is increased, and the heat exchange is uniform and sufficient to ensure the absorption of heat from the low-level heat source in multiple places.

3. Copper Tube Heat Exchanger

Using WDD intelligent heating technology, coaxial spiral heat exchange copper tube, turbulent heat exchange, avoiding water scale, the whole copper tube inside has no solder joints, the flow channel has no water blind area, while being corrosion resistant, the tube length is extended, and the contact area with refrigerant becomes larger, The heat exchange utilization is increased, the heat exchange effect is sufficient, and it is enough to ensure the improvement of the unit's energy efficiency ratio.

4. Throttling Device

Adopt domestic big brand Sanhua electronic expansion valve and four-way reversing valve, automatic adjustment, to ensure flexible reversing, no air leakage, no jamming, function control system, stable operation, save money and effort, effectively solve the problem of winter unit evaporator frosting, ensure the unit can operate normally even in cold winter.

5. Silent Fan

Using heat exchanger and low speed high torque new three-dimensional design turbine fan, while improving the efficiency of the heat exchanger, it can automatically adjust the wind speed according to the ambient temperature, run quietly, use large diameter low speed wind, motor, improve efficiency, reduce frosting, reduce noise.

6. Intelligent Control System

The use of air source heat pump intelligent controller, control logic reasonable selection of high-quality materials, exhaust protection, overcurrent protection, phase sequence protection, water temperature too high protection, high and low pressure protection and other multi-faceted protection functions fully intelligent control.
