From the aspects of building energy-saving,mainly introduced the air source heat pump water heater units,the characteristics and basic system composition,working principle and basic work flow,and the key of air source heat pump hot water system design for a detailed description of the system,and finally summarizes the adaptability and economy.Air source heat pump hot water generator design includes:unit of system design,overall layout design,the unit of condenser bushing design,design and fin evaporator auxiliary equipment selection and control system design,air source heat pump water heater installation and commissioning and maintenance,etc.In the condenser and evaporator finned tube for key design calculation,this paper expounds the heat transfer coefficient of heat exchange tube and the whole structure,determine the number of design calculation.
System USES of vortex,heat exchanger type compressor adopting casing condenser and evaporator,fin,working unit system using R22 heat 17.5 kW.The initial design requirements:heating temperature 15 ° c,heating temperature 52 termination,Design:the evaporation temperature 0 ° c,55,condensing temperature saturated.the degree of six degrees Celsius,heat transfer,5 degrees Celsius temperature 5 ° c.
In this paper is carried out air source heat pump water heater working characteristic analysis,in actual work,due to the environmental temperature
TongHe requirements of different water temperature,the unit of heat changes.In heating conditions,the air source heat pump water heater with the performance of the outlet temperature coefficient decreases with the increase of temperature,reducing environment.
