Re: [TRNSYS-users] Request for information regarding the utilization of Type 534 with plugins for high temp and high pressure applications. Information regarding medium to high temp collectors.

[David BRADLEY <d.bradley@tess-inc.com>]

Muhammad,

 Type534 makes the fundamental assumption that the liquid properties (density, specific heat, viscosity, and thermal conductivity) are constant in the temperature/pressure range over which the tank is operated. I'd suggest you find the values of those properties at 4MPa and 250C and again at 8MPa and 300C. If the properties change only a little then you can use Type534.

 The same assumption is true for the collector model. If the fluid properties cannot be assumed to be constant then you might want to look at some of the components in the High Temperature Solar library instead.

kind regards,

 David

Dear Sir/Madam,

Hi,

I have to use the type 534 with plugins (Storage tank) for temperature ranges as high as 250 to 300 degrees Celsius and pressure around 4 to 8 MPa. Can this type be used for these ranges. If not is there any other type of storage tank that can be used.

Also, I wish to ask if the type 1288 (Linear Fresnel Collectors) could be used for the ranges mentioned above.
