Product Description

The ‘Swarg Systems & Instruments’ unit enables the students to easily study the operation of ice plant. It consists of hermetically sealed refrigerant compressor, using R-12 refrigerant. The condenser is air cooled type. Similar to commercial ice plant, evaporator with forced circulation of brine over it is provided adjacent to ice can tank. The evaporator is fed by a thermostatic expansion valve. A brine agitator circulates brine over the evaporator. The students can study the cycle, calculate theoretical COP and compare the time for ice formation for different ice can thickness.

SPECIFICATIONS
1. Hermetically sealed refrigerant compressor 1/3 ton capacity.
2. Finned tube type air cooled condenser with forced air flow.
3. Thermostatic expansion valve of suitable capacity.
4. Evaporator coil inside of ice can tank.
5. Brine agitator to circulate the brine over evaporator.
6. Capacity of plant – 50 Kg/day with ice cans of different size to study the effect of ice can thickness on ice formation period.
7. Main tank made of stainless steel sheets, of suitable size to hold the ice cans. The tank is provided with 150mm glass wool insulation outside
8. Measurements

  • Dial thermometer for brine temperature.
  • Energy meter for compressor input measurements.
  • Pressure gauges for evaporating and condensing pressure.
  • Digital temperature indicator for temperatures of refrigerant cycle.
  • Density meter to measure density of brine.

9. Controls

  • Overload protector for compressor.
  • Pressostat i.e. high/low pressure cutout.
  • Thermostat.
  • Filter cum dryer for refrigerant.

A Technical manual accompanies the unit.
