Details

　　Many people have heard of the safety and safety of air energy water heater Environmental protection advantages, but air energy water heaters are actually energy-saving compared with traditional heating equipment, and the energy-saving effect is also very significant. The air energy heat pump follows the "reverse Carnot principle" for heating, and uses refrigerant to absorb the heat in the air to produce hot water.

　　 In the heating process, there is a value called the heating energy efficiency ratio COP, which refers to the ratio of the heat produced by the heat pump to the electric energy consumed. The higher the COP, the higher the heating efficiency of the equipment, and the more energy-saving the heating. The country has also introduced standards, which are divided into 5 energy efficiency levels according to the different heating efficiency of heat pumps. From 5 to 1, the heating efficiency of air energy water heaters is getting higher and higher, and the power saving effect is becoming more and more obvious. At present, most air-energy heat pumps can achieve energy efficiency above level 3. Therefore, if you have higher requirements for energy saving, then it is recommended to choose equipment with level 2 or level 1 energy efficiency.

　　一、Air-energy water heater It is very important to choose the most suitable location for installation. Choosing a suitable location is conducive to the efficient operation and effective energy saving of the air-energy water heater. The principle of location selection has been described in detail above. So, I won’t repeat it here.

　　 2. There are drainage facilities: the installation of air-energy water heaters will drain condensate during use, so the installation location should have floor drains, drains and other drainage facilities.

　　 3. The installation location of the instrument: the instrument, which is the control panel, needs to be installed nearby to avoid rain; since most of the operation modes choose "economy mode", the control panel is actually very few Operation, there is no need to install it in a very conspicuous position. It can be installed on the wall of the balcony or corridor.

　　 IV. Plumbing layout: The inlet and outlet pipes of the air-energy water heater are preferably 25PPR pipes (commonly known as 6 pipes). Note that the water pipe screw is still 4 points; the air-energy water heater is a central water heater, and the outlet pipe is actually a main pipe, with a larger diameter , This can avoid the phenomenon of "suddenly hot and cold". Customers who install the return water device, the diameter of the return pipe only needs to be 4 minutes.

　　 V. Power socket: The power socket is a three-pin plug with a wire diameter of 1.5 square meters (or more), preferably with a waterproof box.

　　六、Air energy water heaterBasic requirements for door-to-door installation:

　　 1. The bulk machine must be installed on-site, so you must carry a vacuum pump, a spirit level, a copper pipe expansion interface tool, especially a vacuum pump, which is the key equipment.

　　2. The coil and connecting pipe must be evacuated, and the vacuum must be 550 mmHg and above; if a refrigerant is used to drive the air inside the copper pipe, it will inevitably reduce the amount of refrigerant. Affect the heating efficiency and also pollute the environment.

　　3. The level deviation of the host should be less than 5mm

　　 Seven, trial program:

　　1. Connect the cold water pipe first, and the cold water pipe is connected to the water inlet at the safety valve position (the cold water pipe interface should be installed with an inspection valve);

　　2. Filling the water tank is the most important link (filling must be done before the hot water pipe is connected), after the hot water outlet has water flowing out (indicating that the water tank has been Fill up with water) Close the valve and stop filling;

　　3. Connect the hot water pipe and open the water inlet valve;

　　4. Plug in the power cord and start running

　　5. Check the water pipe wires, listen to the sound, check the fan, observe the instrument, run for 10 minutes without exception, and then complete the test.

　　 8. Do not move the water temperature probe at will: The water temperature probe cannot be separated from the water tank temperature detection blind pipe, so as to avoid overheating the unit heater and damage the unit.

　　 Nine, the hot water temperature should be appropriate: When the hot water temperature is above 50 degrees, it must be mixed with hot and cold water to avoid burns.

　　10. Selection of fuse: Do not use copper wire or iron wire instead, which may cause malfunction or fire.

　　11. Confirm the use power of electrical equipment: The main power supply must meet the power requirements of the heat pump water heater, and the electricity use must meet the national civil/commercial use requirements. Otherwise, the unit will be damaged by over-voltage and under-voltage operation, and even cause fire.

　　12. Leakage protection switch: Customers should install a leakage protection switch with equal power and good grounding performance.
