The air source water

The air source heat pump floor heating temperature cannot be raised? What’s going on? When the weather turns cold in winter, many customers will test run the floor heating at home. If there is a problem, they can also be repaired and maintained as soon as possible, so as not to delay the normal use of the heating season. Then let me briefly tell you the reasons why the air source heat pump floor heating temperature cannot be raised. I hope it will be helpful to you.

1. The amount of hot water used exceeds the water output of the air source heat pump. The water output of the air source water heater is variable. As the temperature decreases, the water output will decay. When the ambient temperature is lower than 10 degrees, the air source heat pump unit will also lose some heat during defrosting. Part of the reason is that the user’s uncontrolled water use exceeds the heating load of the unit.

2. The temperature sensor measuring the water temperature is damaged, and the detected temperature does not match the actual temperature of the hot water. Release hot water from the water tank and test the water temperature by hand. When the actual water temperature is too high, the controller will display the water overheating protection fault code.

3. For customers like hotels that have a return water system installed, the heat dissipation of the heating pipe is large, and the heating capacity of the air-source water heater is less than the sum of the heat dissipation of the pipe and the heating load.

4. In areas with poor water quality, the condenser (hot water heat exchanger) of the air-source water heater is scaled after a period of use, and the heat exchange efficiency is reduced. In severe cases, the air-source heat pump unit will report a high-pressure protection fault.

5. The expansion valve is too large, the heat exchange efficiency between the refrigerant and the air is reduced, the heat obtained from the air is reduced, and the heating capacity is attenuated.

6. The air-source heat pump system has insufficient refrigerant, the heat exchange efficiency of the hot water side heat exchanger and the air side heat exchanger is reduced, and the heating capacity is attenuated.

7. The air source heat pump floor heating temperature cannot be raised, which may be because the heat dissipation of the radiator is not enough. This phenomenon usually occurs in the homes of users who replace radiators. The radiator is changed from large to small, resulting in the heat emitted by the radiator cannot meet the heat loss of the room.

8. The wet room is not dry, or because the wall of the house is relatively wet, the moisture inside needs to be vaporized and absorbs a lot of heat, so the room temperature cannot rise. It takes about a week to heat the room.

9. The floor heating is frequently turned on and off, that is, the room temperature has not reached equilibrium, it is turned off, the heat emitted from the front is not enough to meet the indoor temperature requirements, or the doors and windows are opened and closed frequently, and the indoor heat is also absorbed by the outside due to the heat transfer between households, so the required temperature is never reached.
