Regarding the specific model you mentioned, the Midea window heat pump air conditioner is designed to provide both cooling and heating functions. It uses a refrigeration cycle to transfer heat either indoors or outdoors, depending on the mode selected. In cooling mode, it extracts heat from the indoor air and releases it outdoors. In heating mode, it extracts heat from the outdoor air (even in cold weather) and releases it indoors.
If you're experiencing issues with your Midea window heat pump air conditioner, I recommend contacting the manufacturer's customer support or consulting a professional technician who can assist you with troubleshooting and repairs. Attempting to modify or hack the system yourself can lead to unintended consequences, damage the device, and potentially pose safety risks.
Always prioritize safety and follow the manufacturer's guidelines and recommendations for the proper use and maintenance of your appliance.
