    FORM 155.32-ICOM2.EN.UL SECTION 2 - PRODUCT DESCRIPTION ISSUE DATE:1/10/2018 SECTION 2 - PRODUCT DESCRIPTION The principle of refrigeration is the exchange of heat. In absorption liquid chilling, there are four basic heat exchange surfaces: the evaporator, the absorber, the generator, and the er. See Figure 1 on page Like any refrigeration system, absorption chilling uses evaporation and condensation to remove heat.

  • Page 17: How It Works (Direct Fired Units)

    FORM 155.32-ICOM2.EN.UL SECTION 2 - PRODUCT DESCRIPTION ISSUE DATE:1/10/2018 HOW IT WORKS (DIRECT FIRED UNITS) The double effect (direct fired) absorption chiller-heater uses water as the refrigerant and LiBr as the absorbent. The vapor pressure of the LiBr solution is lower than the vapor pressure of the refrigerant. The vapor pressure of the LiBr solution is directly related to the amount of refrigerant (water) present in the solution with the LiBr salt and the solution temperature.

  • Page 18: Absorber

    The liquid is then pumped to the generators. The following section describes the unique 2-step evaporator-absorber design of the YHAU-CGN/H direct fired absorption chiller-heater. TWO-STEP EVAPORATOR – ABSORBER The evaporator, as well as the absorber, is split into two sections. This design, similar to a series-counter-flow chiller-heater arrangement along with the parallel flow cycle, enables lower LiBr solution concentrations.

  • Page 19: Plate Type Heat Exchangers

    FORM 155.32-ICOM2.EN.UL SECTION 2 - PRODUCT DESCRIPTION ISSUE DATE:1/10/2018 PLATE TYPE HEAT EXCHANGERS The dilute (weak) LiBr solution leaving the absorber section is pumped through various plate type heat exchangers (such as the low temperature heat exchanger, LTG refrigerant condensate heat exchanger, and high temperature heat exchanger) before it enters the high temperature generator and low temperature generator sections.

  • Page 20: Condenser

    SECTION 2 - PRODUCT DESCRIPTION FORM 155.32-ICOM2.EN.UL ISSUE DATE:1/10/2018 CONDENSER The cooling water from the absorber section enters into the condenser section. This helps condense the refrigerant vapors produced in the LTG as well as the condensed refrigerant from the drain heat exchanger. The liquid refrigerant is then sent back to the evaporator section through a U-pipe (liquid seal).
