1. Classification of triple supply
The triple supply is a heat pump unit that can provide three functions of air conditioning, floor heating and hot water. It is also known as triple heating pump, triple air conditioning, triple hot and cold water supply, triple ground heating and hot water supply, triple air conditioning and hot water supply, triple air conditioning and hot water supply, triple air conditioning and ground heating and hot water use, air conditioning and hot water heater, air conditioning and hot water integrated machine, air conditioning and hot water heater, air conditioning and water heater, triple heat pump, etc. from the perspective of central air conditioning, triple air supply is also known as the total heat recovery type Central air conditioning.
According to the source of heat source, the triple supply is divided into air source heat pump triple supply and ground source heat pump triple supply. Among them, the products of ground source are also called water source heat pump triple supply, triple supply ground source heat pump, etc., and the triple supply of air source heat pump is also called air energy triple supply, air source air conditioning water heater, air source heat pump triple use, etc. In terms of use, air source heat pump triple supply is divided into household air energy triple supply and commercial air energy triple supply. Also known as domestic air conditioning water heaters and commercial air conditioning water heaters.
2. Working principle of air source heat pump triple supply
When making hot water separately: the circulating water pump matched with the hot water heat exchange works, the circulating water pump of the air conditioning heat exchange does not work, the fan of the fin heat exchange works, the working medium releases heat in the hot water heat exchange after the compressor operates, absorbs heat in the fin heat exchange, and forms the hot water making process.
When making hot water and refrigeration: the supporting circulating water pump of the hot water heat exchange works, the circulating water pump of the air conditioning heat exchange works, the fan of the fin heat exchange does not work, after the compressor runs, the working medium releases heat in the hot water heat exchange, absorbs heat in the air conditioning heat exchange, forming the process of refrigeration and hot water production.
When cooling alone: the circulating water pump of the hot water heat exchange does not work, the circulating water pump of the air conditioning heat exchange works, the fan of the fin heat exchange works, the working medium releases heat in the fin heat exchange after the compressor operates, absorbs heat in the air conditioning heat exchange, and forms the refrigeration process.
When heating alone: the circulating water pump of the hot water heat exchange does not work, the circulating water pump of the air conditioning heat exchange works, the fan of the fin heat exchange works, the working medium absorbs the heat energy in the fin heat exchange after the compressor operates, and the heat energy is released in the air conditioning heat exchange to form the heating process.
The air conditioning heat exchange is used as a cooling heat exchange in summer and as a floor heating heat exchange in winter. In order to match the flow direction of different water pipelines, the water pipelines of the air conditioning heat exchange need to have valves to switch.
