Students need to be aware of the modes of pool boiling and to make both qualitative and quantitative assessments of convective, nucleate and film boiling.
The unique design of the H656 allows the student to see the processes taking place inside a glass cylinder and measure temperatures and heat flux under steady state conditions. The unit responds very rapidly to a load change and a wide range of conditions can be investigated in a typical laboratory period.
A fully instrumented bench top pool boiling heat transfer unit using low-pressure non-toxic fluid with water-cooled cylindrical glass condenser.
A bench mounted pool-boiling unit comprising a thick walled glass cylinder with electric heater and water-cooled condenser coil. Operates with ozone friendly, low pressure, non-toxic fluid refrigerant.
Internal electric and mechanical safety devices to allow for unsupervised operation by students.
Instrumentation fitted to enable measurement of heat input, surface, liquid and vapour temperatures and condenser water flow rate and temperatures.
Supplied with a detailed experimental operating and maintenance manual giving example experimental results and sample calculations.
Accessories and spares for two years normal operation together with a full two-year warranty.
A: 220-240 Volts, Single Phase, 50Hz (With earth/ground).
Line current up to 3.0A at 230v
B: 110-120 Volts, Single Phase, 60HzN (With earth/ground).
Line current up to 6.0A at 110v
1.8 litres m-1 at a minimum of 5m head.
Note that the condensing pressure is determined by cooling water flow rate and temperature. The maximum recommended cooling water inlet temperature is 22oC. Details of a suitable water chiller can be supplied where this temperature is likely to be exceeded.
