Machine structure:
1.
(1) Structure: high-temperature storage area, cold storage areas, sample test area
(2) Out material: High grade stainless steel plate with white painting;
(3) Inner material: SUS304 stainless steel;
(4) Testing body heat preservation material: rigid polyurethane foam + fiberglass.
(5) Door insulation materials: rigid polyurethane foam + fiberglass.
2 Testing sample is put on sample shelve,the cylinder drive to open the valve of heat-storing zone or cooling-storing zone.
3 Guide cold air into testing zone, to achieve effect of fast cooling . Balance the temperature control system(BTC) + Special designed air circulation system, Cotrol S.S.R. by P.I.D. ,make the system's heating equal to heat consumption, so the machine can long-term stability using.
4 Air adjusting Channel: Centrifugal fan:
Stainless steel heater, aluminum wind round, sealed duct valves, temperature sensors."
5 The device test load: Means that the sample have no heat source, the sample size can not exceed 50% inside test volume , made of non-metallic products (which can be customized according to the user's specific sample)
Cooling system and temperature control:
1.Working way: Size selection for machine model; the cascade of mechanical refrigeration; water-cooling (users should prepare the cooling water tower)
2.Refrigeration Compressors: Imported famous brand low efficiency hermetic or semi-hermetic compressors.
3.Evaporator: Fin-type multi-stage automatic load capacity adjustment evaporator.
4.Condenser: Shell and tube heat dissipation condensation.
5. System expansion: Refrigeration system capacity control purposes
6. Cooled heat exchanger: Made in Taiwan ultra-high efficiency stainless steel plate.
7. Cooled machine control mode: Control system controller automatically adjusts the cooled operating conditions based on test conditions than the traditional design, control stability and reproducibility of high power and achieve effectiveness. Return air compressor cooling circuit
8. Refrigerant and refrigeration piping: R22, R-23, R404A, Environmental Protection; indices are zero ozone depletion refrigerant pipes have automatic and manual defrost function
