to a given safety condition (see Controls section for a complete list), it first crosses a warning threshold which will cause the panel to limit heat input to the machine. In this manner, the YIA unit continues its vital task of making chilled water, while allowing operators the opportunity to find…

BAFFLES FORM 155.16-EG3 (1010) The single effect absorption cycle uses water as the refrigerant and lithium bromide as the absorbent. It is the TEMP. strong affinity that these two substances have for one SENSOR another that makes the cycle work. The entire process occurs in almost a complete…

Mechanical Specifications

The mechanical features listed here apply to chillers sold in North America. Some of the features may differ on chillers delivered to other regions. Among those differences are the method of chiller shipment preparation and the types of piping interface. The YORK YIA Absorption Liquid Chiller is…

STABILIZER VALVE

A solenoid actuated valve sends refrigerant water into the solution heat exchanger circuit in order to combat any minor crystallization. UNLOADER VALVE Steam – The valve is a cage type (for low steam mass flow) with a cast iron body or butterfly type (high steam mass flow) with a carbon steel body.…

STEAM AND CONDENSATE THEORY

Saturation Temperature The temperature at which a fluid changes from the liquid phase to the vapor phase, or conversely, from the vapor phase to the liquid phase is called the saturation temperature. A liquid at the saturation temperature is called a saturated liquid and a vapor at the saturation…

To determine the total heat content contained in a quantity of steam multiply the specific enthalpy by the mass of the steam. seen is equivalent to saturated steam with a quality of 1.0 (100% vapor). It is important to note that as the quality decreases, the heat content of the steam also decreases.…

be nearly as much as if the design steam valve pressure

drop is low. For a 3 PSIG (21 kPa) design steam valve pressure drop, one can expect about a 50% increase in steam demand on start up. If the design were based on a 4 PSIG (28 kPa) steam valve pressure drop, the increase in start up demand would be around 35% above normal. Likewise, a 2 PSIG (14 kPa)…

purities may manifest themselves in the form of dirt, rust

or precipitates. This strainer will prevent chiller system components from getting plugged. Plugged components will reduce system capacity and increase maintenance costs. A pressure gauge must be installed before and after the steam strainer. If the pressure drop as read from these two gauges…

Vacuum Breaker (If Desired) – A vacuum breaker will

often not be necessary, but they can prevent condensate build up in the generator section of the chiller at part load.
