6 Construction and Principles Refrigeration circuit Injection valve Expansion valve (a) Water control valve Refrigerator Expansion valve (b) Internal pump Level switch Circulating pump Level switch Facility water outlet Facility water circuit Facility water inlet Water-cooled condenser Refrigerant dryer Highpressure gauge Highpressure shutoff pressure switch Heat exchanger Main tank Pressure sensor Flow sensor Temperature sensor Circulating fluid outlet Circulating fluid return inlet Sub-tank circuit circuit With the circulating pump, circulating fluid will be discharged to the customer s equipment side. After the circulating fluid will heat or cool the customer s equipment side, it will be returned to the main tank via the heat exchanger. A sub-tank is not used under the normal operation. It will be used when a circulating fluid is recovered from the customer s equipment side. The internal pump is used to transfer a circulating fluid from the sub-tank to the main tank. (Refer to automatic recovery function on page 9.) Refrigeration circuit When the circulating fluid temperature is rising higher than the set temperature, open the expansion valve (a) to introduce Freon gas at a lower temperature to the heat exchanger. With this, the circulating fluid will be cooled down. Oppositely, when the circulating fluid is getting lower against the set temperature, open the expansion valve (b) and introduce Freon gas at a high temperature without going through the water-cooled condenser to the heat exchanger. With this heat, the circulating fluid will be heated. 9

(In this case, selected Thermo-chiller model will be either -L or -H.) Water bath C V After 15 min, cool C down to C. Note) This is the calculated value by changing the fluid temperature only. Thus, it varies substantially depending on the water bath or piping material or shape. Precautions on Model Selection 1. Heating capacity When setting the circulating fluid temperature at a higher temperature than the room temperature, the circulating fluid temperature will be heated with the Thermo-chiller. Heating capacity varies depending on the model of the series. Also, the heating capacity varies depending on the circulating fluid temperature. Consider the heat radiation amount or thermal capacity of the customer s equipment. Confirm beforehand if the required heating capacity is provided, based on the heating capacity graph for the respective model.. Pump capacity < flow> Pump capacity varies depending on the model selected from the series. Also, circulating fluid flow varies depending on the circulating fluid discharge pressure. Consider the installation height difference between our Thermo-chiller and a customer s equipment, and the piping resistance such as circulating fluid pipings, or piping size, or piping curves in the equipment. Confirm beforehand if the required flow is achieved using the pump capacity curves for each respective model. < discharge pressure> discharge pressure has the possibility to increase up to the maximum pressure in the pump capacity curves for the respective model. Confirm beforehand if the circulating fluid pipings or circulating fluid circuit of the customer s equipment are fully durable against this pressure. 96

31 Series Specific Product Precautions 1 Be sure to read this before handling. Refer to front matters and 3 for Safety Instructions and pages 86 to 865 for Temperature Control Equipment Precautions. Warning Design 1. This catalog shows the specification of a single unit. 1) For details, please consult our Product Specifications and thoroughly consider the adaptability between the customer's system and this unit. ) Although the protection circuit as a single unit is installed, the customer is requested to carry out the safety design for the whole system. Caution Selection 1. Model selection In order to select the correct Thermo-chiller model, the amount of thermal generation from the customer s system, the operating circulating fluid, and its circulating flow are required. Select a model, by referring to the guideline to model selection of this catalog.. Option selection Options have to be selected when ordering the Thermo-chiller. It is not possible to add them after purchasing the unit. Warning Handling 1. Thoroughly read the operating manual. Read the operating manual completely before operation, and keep a copy on-site, for future reference. Operating Environment / Storage Environment Caution 1. Do not use in the following environment because it will lead to a breakdown. 1) Environment like written in Temperature Control Equipment Precautions. ) Locations where spatter will adhere to when welding. 3) Locations where it is likely that the leakage of flammable gas may occur. ) Locations where the ambient temperature exceeds the limits as mentioned below. During operation 1 C to 35 C During storage C to 5 C (But as long as water or circulating fluid are not left inside the pipings) 5) Locations where the ambient relative humidity exceeds the limit as mentioned below. During operation 3% to 7% During storage 15% to 85% 6) (Inside the operation facilities) locations where there is not sufficient space for maintenance. 7) In locations where the ambient pressure exceeds the atmospheric pressure.. The Thermo-chiller does not have clean room specification. It generates dust from the pump inside the unit and the cooling fan in the refrigerator. Caution Circulating Fluid 1. Avoid oil or other foreign objects entering the circulating fluid.. Use ethylene glycol which does not contain additives such as antiseptics. 3. The condensation of the aqueous solution of ethylene glycol should be 6% or less. If the density is too high, the pump will be overloaded, resulting in occurrence of Pump Breaker Trip FLT. Also, if the density is to low, the unit will freeze at lower tempera-tures, resulting in product failure.. Avoid water moisture entering the fluorinated fluid. Otherwise, the unit will freeze, resulting in product failure. 5. Use clear water (including for diluting ethylene glycol aqueous solution) which must meet the water quality standards as mentioned below.
