Multi-connected air conditioner with refrigerant and water system

A multi-mode Multi-connected Air Conditioner with Refrigerant and Water (MACRAW) system, comprising:

• multiple air conditioning units, each of the multiple air conditioning units comprising a refrigerant circulation loop, at least one outdoor heat exchanger and at least one indoor heat exchanger, refrigerant circulation loops within the multiple air conditioning units being independent of each other;
• a first medium channel being provided inside the at least one outdoor heat exchanger and the at least one indoor heat exchanger, respectively;
• at least one the outdoor heat exchanger and the at least one indoor heat exchanger in each of the multiple air conditioning units communicating with the refrigerant circulation loops independent of each other through the first medium channel and the communication, closure, and flow regulation of the first medium channel in each of the at least one indoor heat exchanger being controlled by disposing an expansion valve;
• the refrigerant circulation loop being provided with a compressor for driving the refrigerant to flow and a four-way valve for switching a flow direction of the refrigerant,
• wherein the MACRAW system further comprises:
• a first circulation loop, a second circulation loop, and a main heat exchanger,
• the first circulation loop is provided with a first circulation pump and a natural energy collector,
• the second circulation loop is provided with a second circulation pump,
• the first circulation loop and the second circulation loop exchange heat with each other through the main heat exchanger,
• a second medium channel is provided inside the at least one outdoor heat exchanger and the at least one indoor heat exchanger,
• the at least one outdoor heat exchanger of each of the multiple air conditioning units is connected in parallel and communicates with the first circulation loop through the second medium channel, and the first circulation loop exchanges heat with the first medium channel in the at least one outdoor heat exchanger through the second medium channel,
• a first air heat exchange channel is provided inside the at least one outdoor heat exchanger and the first air heat exchange channel exchanges heat with the first medium channel and/or the second medium channel in the at least one outdoor heat exchanger, and the heat in the first air heat exchange channel is transferred to the outside with an airflow by disposing a first fan,
• the at least one indoor heat exchanger of each of the multiple air conditioning unit is connected in parallel and communicates with the second circulation loop through the second medium channel, and the second circulation loop exchanges heat with the first medium channel in each of the at least one indoor heat exchanger through the second medium channel, the communication and closure between the second medium channel in each of the at least one outdoor heat exchanger and the first circulation loop are controlled by disposing a first valve and the communication and closure between the second medium channel in each of the at least one indoor heat exchanger and the second circulation loop are controlled by disposing a second valve,
• a second air heat exchange channel is provided inside the at least one indoor heat exchanger, and exchanges heat with the first medium channel and/or the second medium channel within the at least one indoor heat exchanger and heat in the second air heat exchange channel is transferred to an indoor environment with the airflow by disposing a second fan.
