The minimum temperature of the cooling tower can be cooled to several degrees, depending on your leakage temperature, and the type of cooling tower used and the cooling tower filling materials. Generally, there are industrial production cooling towers, industrial production high temperature cooling towers, high temperature cooling towers, etc. Different model specifications, different actual effect of temperature reduction. Naturally, it is also related to nearby environmental hazards and the humidity of the nearby environment.
Based on the local wet bulb temperature decision, the basic theory of temperature output can infinitely increase the wet bulb temperature, but in specific circumstances, there is a 1.6 degree close temperature between the output temperature and the wet bulb temperature. In other words, the local wet bulb temperature is 28, and the output temperature *It can be reduced to 29.6 degrees at least! (Wet bulb temperature is the minimum temperature that today's natural environment can achieve only based on volatile water)
1. The basic principle of refrigeration of the open type glass fiber reinforced plastic cooling tower is:
according to the sprayer method, the cooling circulating water is introduced into the glass fiber filling raw material, and the heat transfer is maintained according to the contact between the water and the steam, and the centrifugal fan promotes the tower hurricane Circulation system, and conduct heat transfer with water after the hot hurricane conducts cooling. This type of refrigeration method requires less investment in asset projects at the ** stage, but higher operating costs (water consumption, energy consumption).
2. The basic principle of refrigeration of the sealed glass fiber reinforced plastic cooling tower is one is the internal circulation of the car and the other is the external circulation. Without fillers, the key core component is the air conditioning copper tube cooling tower.
a. Internal circulation
: connect with the target machine equipment to form a closed circulation system software (the circulating material is demineralized water). Carry out cooling for the target machinery and equipment, and take the heat from the target machinery and equipment to the cooling generator set.
b. External circulation
: In the cooling tower, the cooling tower itself carries out temperature reduction. It does not touch the internal circulating water, and only uses the copper tube surface cooler in the cooling tower to carry out heat transfer and heat pipe heat dissipation. In this type of cooling method, the operation of the motor is set according to the temperature according to the automatic control system. 2 cycles. In the case of high natural environmental temperature in spring and summer, 2 cycles must be operated separately. The natural environmental temperature in autumn and winter is in two seasons.
