1. In winter, the domestic ground source heat pump is in heating operation. Before use, check the refrigeration cycle pipeline to ensure that all valves are closed, and then open the heating cycle pipeline valve.
2. Before use, check the circuit of the unit to avoid phase loss and reverse equality; check whether the external grounding wire is reliably connected; if there is any abnormality, please replace it in time.
3. When starting the ground source heat pump, check the condenser. The water in the condenser should flow normally. At the same time, observe the outlet pressure difference between the condenser and the evaporator, and clean it if necessary.
4. Add antifreeze in time. If the ground source heat pump does not drain the water in the unit in winter, antifreeze must be added, otherwise it will cause harm to the ground source heat pump unit.
5. Check whether the air inlet and outlet of the indoor unit are blocked regularly, and ask professional maintenance personnel to clean the filter screen of the indoor unit regularly.
6. When using ground source heat pump in winter, avoid the damage of air conditioning system caused by power failure, water shortage or improper use, so as not to affect the normal use.
We OSB heat pump own wide range of ground source heat pump, which including inverter type and non-inverter type. 8kw to 45kw could be widely chose. High efficient plate heat exchnager for good performance of heating. Max hot water temp up to 50 deg c. Minimum cold water temp can be 8 deg c. Adopt heating, fan coil cooling, domestic hot water functions. No fan silient design. Simple design, easy to maintain once have any problems in the future.
