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.
What are the differences between air-cooled heat pump chillers and air-cooled heat pumps
Air cooling: cooling by fan (corresponding to water cooling - cooling by cooling tower)
Heat pump: Originally, it refers to a device that can convert low-grade heat into high-grade heat. In air conditioning equipment, it refers to a system that can provide heating in winter and cooling in summer.
Chiller: equipment that can produce chilled water (about 4-15 ℃).
Air cooled heat pump cooling (heating) water unit: air cooled air conditioning unit that can produce cold water or hot water.
Screw type: compressor type of air conditioning unit, other types include piston type, scroll type, etc.
Air cooled water heater: a special unit for generating hot water (including winter and summer) introduced in recent years.
ZTF-2 adjustable damping butterfly valve electric butterfly valve:
1. The butterfly valve is designed with low frequency value, and has good weather resistance and shockproof effect after plastic spraying treatment.
2. . Anti slip and wear-resistant bolts and fixing bolts are used at the bottom and bottom, which greatly improves the safety performance.
3. The installation is simple and the level and height can be adjusted according to the actual needs.
4. It can effectively isolate the vibration of water chillers, cooling towers, heat pump units, generator sets, and other large power equipment, and protect and extend their service life.
