How can I prevent my mini-split heat pump from freezing?

To solve and prevent the problem of freezing mini-split heat pumps, the following measures are recommended:

• Clean and replace the air filter regularly to ensure good air circulation.
• Regularly check and maintain the refrigeration system to ensure that the refrigerant is sufficient and there are no leaks.
• Set the indoor temperature reasonably, and avoid setting it too low when the outside temperature is very low.
• Regularly check the drainage system to ensure that water can be drained out smoothly.
