The arrangement of the refrigerating room and the installation of the wet curtain air cooler

The arrangement of the refrigerating room and the installation of the wet curtain air cooler

1, refrigeration room layout

The room where the refrigeration equipment is set is called the refrigerating room or the freezing station. A small, usually attached to the basement of a main building or the base of a building. Large scale refrigeration room, especially ammonia refrigeration room, need to be built separately.
The refrigerating machine in the refrigerating room and the refrigerating and cooling water pump which is matched with the refrigerating machine have the advantages of large weight and large vibration and noise during operation. If it is a group of real high-rise buildings, the best refrigeration room layout in the podium building basement, and to do a good job of noise elimination and vibration isolation, especially vibration pump, cooling water amount of frozen hanger. The adjacent room and the upper room of the refrigerating machine room should be the place where the noise isolation and vibration isolation requirements are not high.
Refrigerator and refrigeration equipment, such as refrigeration, cooling water pump and other equipment is the construction of large power, its location should be close to the load center, and the low-voltage distribution between the near, and the best set in the vicinity of the elevator.
Refrigeration room should be set to send, exhaust equipment, in order to eliminate indoor waste heat, add fresh air. Room temperature should be less than or equal to 36 DEG C. Room should take measures to prevent noise from the operation of the unit to the air conditioning room or outdoor environment. The room should be equipped with artificial lighting, in the control switch and the operation of the instrument around to have adequate illumination.
Based on the chiller room should be higher than the ground 150 to 200 mm. Based on the foundation and should be located in the drainage ditch and the computer room sump or floor drain in order to discharge may produce water leakage, oil.
The floor of the equipment such as lifting and cooling, cooling water pipe and so on should have enough bearing capacity, and should deal with the problem of vibration isolation.
The fire fighting measures of the refrigerating room should meet the design requirements of the relevant regulations of the state.
In the refrigeration room, the quantity and the weight of the water chiller and so on are larger, so it is necessary to consider the convenience of the equipment. The service life of the mechanical and electrical equipment is shorter than that of the building, and the reserved equipment installation hole shall be equipped with the measures to be replaced when replacing the mechanical and electrical equipment.
2, the use of wet curtain cooling fan and installation points
Key points of wet curtain air cooler:
1, wet curtain cooling fan and pump circuit should be centralized control, control switch should be installed indoors. Before the use of cold air blower, it is necessary to ensure that there is no moisture in the curtain and the pool, cleaning 1 ~ 2 times a year; when not in the winter, the pool of water to release the net, with plastic sheeting to the box wrapped in order to avoid debris into the machine.
2, join the pool water should be clean water, in order to maintain the wet curtain cooling pipe and high efficiency. If the wet curtain water supply shortage or uneven, to check whether the pool water (automatic water and water float valve, water pump pool) is running and the water supply pipe and a water inlet, especially water holes on the pipeline has blocked, check the water is located in the center of the wet curtain line.
Wet curtain air cooler is a new choice of the times: wet curtain cooling fan that is a wet curtain + fan longitudinal ventilation cooling system, is the world's most economical, most environmentally friendly cooling system. The working principle is: a thin layer of water film on the wet film surface corrugated, dry when the outdoor fresh air is opposite fan suction through the wet film, the heat in the air is wet film on water absorption and evaporation of water into the interior, the formation of cool moist air, make people have a fresh feeling.
Wet curtain cooling fan installation instructions:
The cold air blower is installed outside the window and the wall, and is connected with the window or the wall or the wall hole by a pipe joint. Cold air outlet should be higher, not direct blow the human body. Before installation, the angle bracket is welded with angle steel, and the parameter size is determined by the installation site. Taking into account the safety of the people into the machine, the 40-50 angle.
The distance between the wet curtain air cooler and the wall should be greater than 30CM, so as to avoid the airflow obstruction. Wet curtain cooling fan ventilation generally have two kinds of vertical and horizontal flow, the transverse ventilation flow area, the wind speed is small, easy to cause a large area of dead, while the longitudinal ventilation fault area is small, the wind speed is high, the dead area is very small. In the case of the use of conditions permit, should be as far as possible the use of advanced longitudinal ventilation.
