DirectFired Absorption Chiller-Heater ol withlatest microprocess equipped or environment, CONTENTS In an application of inverter control of solution puffiF, saving energy has been realized in the whole range from partial loads to rated loads of cooling mode. Installation costs may be reduced at no control of cooling water temperature and further saving in energy consumptiong as operation is feasible as 15'C at the inlet of cooling water. Note 2 This graphic chart is applicabte to the model through Note 3 An area surroundedby the dotted lines is the area for available loads.

Refrigerant evaporates in an evaporator and cools down chilled water. The evaporated refrigerant is absorbed into the solution in the absorber. The solution absorbed the refrigerant become weak and sends to the high and low temperature generator respectively through the heat-excangers pumped up by the solution pump.

The weak solution turns to a concentrated strong solution after heating by the burner in the high temperature generator. The solution becomes medium strong solution in the low temperature generator heated by refrigerant steam generated in the high temperature generator.

The strong solution in the high and medium strong solution in the low temperature are mixed together and back to absorber through the both solution heat-exchangers, in which absorbs the refrigerant evaporated from the evaporator.

The generated refrigerant in the low temperature generator move to the condenser and condensed by the cooling water. Condensed refrigerant back to evaporator. The high temperature steam refrigerant generated in the high temperature generator is moved through valve and condensed in the evaporator and heating up hot water for heating. The refrigerant is down to and mixed up with medium weak solution in the absorber. Then pump up to the high temperaturegenerator by solution pump.

The medium weak solution generates steam refrigerant vapor in the high temperature generator. S llo.

EBARA absorption chiller

Ebara provided seven direct-fired chillers for this commercial center of thousand square to meet summer cooling and winter heating demands. Using coking waste heat for heating and refrigeration, the company adopts double conditions absorption chiller unit. All these kinds of water have low temperature and large amount of residual heat. Heat pump technology are always used for recovering these residual heat source.

RCD Ebara Absorption Chiller

This chiller achieves excellent energy efficiency over the entire operating range, from the rated load to prolonged partial load, with an inverter-controlled solution pump. This chiller optimizes the circulating amount of solution at the time of start-up to reduce the start-up time. The chiller judges the operation status at the time of stop to determine the optimum dilution time. The chiller can prevent extra dilution operation that reduces the energy-saving effect. Equipped with a start-stop circuit for the cooling tower fan as standard, including a thermos sensor, the chiller helps to reduce the cost of equipment. The chiller has a control panel that can digitally display data required for operation control, such as the chilled water temperature, cooling water temperature, solution temperature, and operating time, on an individual basis. USRT Features Shorter start-up time This chiller optimizes the circulating amount of solution at the time of start-up to reduce the start-up time.
