How to clean the air source heat pump scale method is better

Release Time：2021-07-21

Commercial ultra-low temperature air source heat pumps with slow hot water production, frequent high pressure protection, exhaust protection and overload protection need to be cleaned after checking the problems such as lack of refrigerant, excessive refrigerant, blockage of fluorine system, blockage of water system, shortage of water or insufficient flow, and the unit has been in operation for more than 3 months, the specific cleaning steps and methods are as follows:
Step 1: Clean the connection of the container. First, close the valve of the water tank inlet and outlet pipe and the valve of the circulating water pipe, then disassemble the pipe from the inlet of the circulating pump, connect the air source heat pump to the circulating outlet pipe with a temporary pipe, and finally put the temporary circulating outlet pipe and the water pump inlet pipe into the cleaning container at the same time to clean the container circulating pipe completely and thoroughly.
Step 2: the configuration of the pickling solution, it has been verified that oxalic acid is used as the cleaning solution, and the buffer and surfactant are added at the same time, the cleaning effect is better, and the corrosion effect on the heat exchange tube can be reduced. Other special detergents can also be used, but they must be cleaned strictly according to the requirements of the corresponding instructions.
Step 3: soak and cycle cleaning, first start the water pump to suck the pickling solution into the casing for static soaking for 2 hours, and the air source heat pump moves every half an hour, and finally the pickling process can be completed by continuous dynamic circulation for 3~4 hours. The pickling temperature is controlled at 60 ℃, and the cleaning effect is better.
We all know that the outdoor temperature is low in winter, so do you need to add antifreeze to the air energy heat pump floor heating? It is best to add a certain amount of antifreeze. You can add a corresponding proportion of antifreeze according to the size of the floor heating area. If it is really inconvenient to add, you must pay attention to the antifreeze work in winter. In order to reduce the operating cost of the air energy heat pump, it is recommended that users adjust the air energy heat pump to the air source heat pump to the heat pump to the low temperature during the low temperature during the day when heating, after returning home, the heat pump will be heated in time to realize the supply of heating.
How do users use the thermostat when the air energy heat pump is installed in the floor heating room? The indoor air energy heat pump adjusts the room temperature through the thermostat, but the heating temperature of the whole system still needs to be controlled on the unit. When we use it, we can set the temperature on the unit to 55 ℃ and the room temperature to 20 ℃, so that the unit can heat the room with 55 ℃ hot water, make the room reach 20 ℃ as soon as possible, that is to say, when the host temperature is set higher, the indoor temperature rises faster, otherwise it will be slower.
