Nanchang High speed Railway Project: ZTF damping butterfly valve electric butterfly valve of air cooled heat pump cold (hot) water air conditioning system
Shanghai Dongfeng Pump Valve Factory assists in the Nanchang high-speed railway project by providing the project with electric butterfly valve products for damping butterfly valves of air-cooled heat pump cold (hot) water air conditioning systems. The products are mainly used in the base of air-cooled heat pump cold (hot) water air conditioning host, which plays a role in vibration reduction and noise reduction.
Principle of air-cooled heat pump cold (hot) water air conditioning system:
In the traditional central air conditioning system, after the refrigerant of the condenser of the host machine is cooled by the fan, the refrigerant absorbs the heat of the medium water in the main evaporator, making the medium water become low-temperature chilled water (or warm water). The chilled water (or warm water) is circulated to the indoor end device by the pump, where the cold (hot) water exchanges heat with the indoor air.
