新式空调的工作原理（The working principle of the new air conditioner） Some hot and cold water machine Fixed frequency cold water heater or frequency conversion cold water heater The large central air conditioner is reduced and the condenser is cooled by water, and the hot and cold water is sent to the fan coil by water pump. New ventilation, inspection hole, ceiling condensed water discharge and noise index are the same as those on multi line. But the hot and cold water pipe is added; because of the great temperature difference, the sealing problem is prominent, and the water leakage occurs, and the damage to the decoration is greater. In addition, large central air conditioning evaporators are regularly cleaned and pickled. The domestic hot and cold water heater has no good policy, and the long-term use of the heat exchanger will be greatly reduced. If combined with the central water treatment system, the difficulties mentioned above can be overcome. Single room with air conditioning, other rooms have hot and cold water flowing through the fan coil, will produce energy; now popular to close the water solenoid valve; remove the external factors of cost; will make the local flow speed is too high, the noise problem. Two. The working principle of door type central air conditioner 1. cold (hot) water unit is the basic working process of refrigeration unit: outdoor cold (hot) water medium cooling (or heating), then the refrigerant will pump after cooling (hot) water to the fan coil unit installed in the interior of the heat exchange to achieve indoor the purpose of the air and indoor air from the fan coil unit air return way take place. The basic working process of the 2. air pipe (duct) unit is: when cooling, the outdoor refrigerating unit absorbs the refrigerant vapor from the indoor unit, and then transports the liquid refrigerant to the indoor units after compression and condensation. When heating, the absorption refrigeration unit outdoor refrigerant vapor from the condenser
