Products Features
Unit working principle
1. The low-pressure superheated refrigerant vapor coming out of the evaporator is sucked in by the compressor and compressed into high-temperature and high-pressure superheated steam.
2. The superheated steam is discharged into the condenser to exchange heat with water. The refrigerant condenses (exothermic process) into a saturated or supercooled high-temperature and high-pressure refrigerant liquid. The hot water unit absorbs the heat released by the condensation of the refrigerant through water. Raise the water temperature.
3. The refrigerant liquid is throttled and depressurized by the expansion valve and becomes low-temperature and low-pressure refrigerant liquid.
4. The refrigerant liquid flows into the evaporator, where it absorbs the heat of the surrounding air and vaporizes into low-pressure superheated refrigerant vapor.
The refrigerant circulates as mentioned above, and the water flowing through the condenser is continuously heated, and the water temperature rises, thereby producing hot water.
Installation of the unit
Selection of unit installation location
1. If this water heater is installed indoors, problems such as overflow, noise, and indoor temperature drop may occur, which may affect your life. Please take preventive measures in advance;
2. Provide sufficient installation and maintenance space;
3. The air inlet and outlet must be accessible and strong winds must not blow everywhere.
4. Dry and ventilated place.
5. The supporting surface should be flat (the horizontal inclination angle should not be greater than 2°), able to withstand the weight of the water heater, and the unit can be placed vertically without increasing noise and vibration.
6. Operation noise and exhaust air will not affect neighbors.
7. There is no leakage of flammable gas.
8. Easy to install connecting pipes and electrical connections.
9. If this hot water unit is installed on a metal part of a building, electrical insulation must be done and must comply with relevant technical standards for electrical equipment.
