display cases Installation of refrigeration equipment
condenser installation For vertical condensers, discharge should be performed on the basis of the drawings to determine the orientation of the display cases condenser. The installation of the condenser is roughly the same as that of the compressor, but a plumb line must be used to ensure that the installation is vertical, and no deflection or twisting is allowed. The operation and maintenance platform must be firm and reliable, and can withstand the horizontal thrust generated by the exhaust pipe being heated. The horizontal condenser is installed on a bracket, often on the same vertical surface as the reservoir, and a 10-20 mm thick asbestos board is placed on the bracket (semi-circular pad technique), and leveled with a horizontal ruler. Need to be slightly inclined to the drain end.
The evaporator can be installed horizontally and vertically. Horizontal evaporators are generally installed on the indoor concrete foundation and connected to the foundation with anchor bolts. In order to prevent the cold bridge from being produced, a 50 mm thick anti-corrosion skid should be placed between the evaporator support and the foundation, and the area of the skid should not be less than the area of the evaporator support. After the installation is completed and the pressure test is qualified, conduct heat insulation. Other installation requirements (such as horizontal allowable deviation, etc.) are the same as horizontal condensers. display cases Vertical evaporators are generally installed on the basis of indoor insulation. The foundation of the vertical evaporator is composed of a concrete cushion, two felts and three oils , thermal insulation materials and asphalt sleepers with the same thickness as the thermal insulation layer. The number of sleepers depends on the quality and length of the evaporator. After the foundation is completed, place the evaporator box that does not leak test water pressure on the foundation, and then hoist and fix the evaporator tube bundle. The tube bundle installation is slightly inclined to the oil drain end.
