In addition to the refrigeration compressor chiller system, meet the basic principle of refrigeration equipment still is often referred to as main equipment, condenser and evaporator; ensure the static equipment and other functions of the system, called auxiliary equipment, such as reservoir, vapor-liquid separator, low-pressure circulation barrel etc..
The chiller is pressure vessel, before installation should check whether the factory provides completion pattern of pressure vessel (if the change in the original blueprint must be modified, technical audit to confirm the marker, and to cover plaintion the stamp), the inspection certificate of quality supervision, product quality certificate pressure vessel safety. The manufacturing unit for pressure components of pressure vessels shall provide technical information to the user in accordance with the relevant contents of the product quality certificate. After the completion of the on-site welding pressure vessel, the construction unit shall also provide the technical documentation and data as described above. Technical data on group welding and quality supervision shall also be provided in accordance with relevant regulations. Of course, on-site welding pressure vessel welding personnel must have the corresponding professional certificate.
The water cooler should be checked and properly kept to the spot. The seal has been opened should be re sealed to prevent dirt access, reduce corrosion. After placing too long for the design, preparation, installation, should check whether there is corrosion or contamination of the internal, and use compression to irrigate the foundation, according to the specific equipment at the location of the screw hole layout model, and pre embedded anchor bolt. The sample must be flat, the size must be correct, and checked with a horizontal ruler. When placing concrete, the anchor bolt shall not move.
When installing the low temperature chiller, the cushion should be added on the base to minimize the phenomenon of "cold bridge". The used wood shall be boiled in the asphalt in advance to prevent decay. Adequate equipment shall be available around the cryogenic equipment to ensure the construction of the insulation layer. Low temperature equipment and its connection between the valve should be left insulation thickness of size, so as to avoid the valve is not into the insulation of low-temperature equipment, affecting the operation and maintenance of the valve.
