Description

Split pressurized solar water heater is composed of heat pipe evacuated tube solar collector, pump station (including circulation pump, controller, expansion vessel, pressure gauge, sensors and etc) and pressurized water tank. Its tank and solar collector are separated, the collector can be put on the balcony and windows.With an intelligent controller and solar working stations, the whole system works automatic. Working principles: 1) When the temperature difference between the solar collector and tank is exceeded the set value temperature difference, the controller shall start the circulation pump automatically, transfer heat from collector to tank 2) When the temperature difference between the solar collector and tank drops below the set value temperature difference, then circulation pump stop 3) The circulation pump makes heat-conducting liquid circulate automatically 4) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank 5) In case the temperature of the water tank does not reach the max., then start the auxiliary heating device Advantages: 1) Highly efficient absorber of high performance with daily average efficiency over *0% 2) Operation system can be connected directly with city water pipe 3) No water inside the evacuated tubes; the solar water heater can still in service even with several tubes breakage 4) Highly efficient insulation with polyurethane foam 5) Simple structure, easy to assembly and install Specifications Tank capacity(L): ******0 Tube specification(Diameter x Length) (mm): Heat pipe Ø*8 x ***0 Tube quantity: ****0 Tube vacuum degree: 5 x ***3 Tube absorption >0.*8 Tube heat loss <0.*8 Tube heat transfer power: ****0Kw/m2 Working pressure(MPa); 0.6 Anti freeze(C): **0 Anti ice drops(Diameter mm): *0 Tube start working temperature(C) <*5 Lighting Area (Made by Alum alloy) (m2): 3.4 Anti-wind support frame (stainless steel): *6.5m/s *0 grade Inner tank specification (Diameter x Length) (mm): **0 x ***4 Thickness of z tank (mm): 1.8 Material of outer tank: steel coated with AL & Zn Insulation (mm): polyurethane *5mm Color of caps on the side of the tank: Black Heat element(fitted in the water tank): ***0W/**0V/*0Hz Controller: *0 C ***0 C Dimensions of inlet and outlet of water: G1/2
