Gas Fired Absorption Chiller

 

Introduction:

The Vicot gas-fired water chiller is a high efficiency gas-fired water chiller for residential and light commercial air conditioning duty. The chiller is designed to be installed outdoors and connected with a chilled water coil located in the indoor air handling system for cooling and dehumidifying the occupied space. Chilled water is produced by an air-cooled ammonia-water absorption chiller based on the highly efficient generator-absorber heat ex-changer (GAX) absorption cycle. It can automatically modulate its cooling capacity down to 50% for improved comfort, humidity control and operating efficiency at part load conditions. Natural gas supplies the main energy input to the absorption chiller. A small amount of electrical energy is required to drive the pumps and fans. The thermostat, indoor blower, chilled water coil and piping are to be field supplied.

Major Component Description and Function

1. Generator

Heats and Distills Solution to Provide Ammonia Vapor (99.5%) and Weak Solution (4%).

2. SCA/GAX Absorber

Provides Suction to Evaporator Using Weak Solution as well as Heat Recovery.

3. Solution Pump

Pumps Strong Solution from Low to High Pressure.

4. Condenser

Rejects Heat and Provides Condensate.

5. PTXV

Provides Expansion of Ammonia and Controls the Refrigeration Effect (High efficiency expansion valve).

6. Evaporator

Accepts Heat Input to Liquid and Provides Vapor to Absorber

8. Air Coil

Condenser Portion Rejects Heat and Provides Condensate, Absorber Portion Completes Absorption of Ammonia and Rejects Heat.
