What should we do if the cooling tower is INEFFICIENT ?
Cooling tower is an important equipment for central air conditioning system to dissipate heat outward. Once there is a problem, even the refrigeration unit and heat pump effect is better, the refrigeration effect of the system is not good. Generally speaking, the main reasons for the poor peformance of the cooling tower can be summarized into five aspects. The details are as follows:
1. Cooling tower is too dirty:
It is known that the outlet that affects the heat emission of the cooling tower is the radiator, namely the filling, which is ...

Safe & Effective Disinfection
For over a century scientists have known that certain frequencies of light have a devastating effect on microbial life. We now know that exposure to ultraviolet light in the range of 254 NM (UV-C band) disrupts the DNA of micro-organisms thus preventing them from reproducing, thereby effectively killing them.

UV Light – A Well Established Disinfection Technology
UV light disinfection is now widely used in hospitals and laboratories to sanitize instruments and work surfaces and to prevent the spread of potentially lethal airborne infectious diseases. The technology...

The primary task of a cooling tower is to reject heat into the atmosphere.
This heat rejection is accomplished through the natural process of evaporation that takes place when air and water is brought into direct contact in the cooling tower. The evaporation is most efficient when the maximum water surface area is exposed to the maximum flow of air in the longest possible period of time. Cooling towers are designed in two different configurations, CounterFlow and CrossFlow. The specific configuration indicates the direction of the air flow in relation to the water flow.

A refrigerant is an element in the form of liquid or gas. A specific area in the refrigeration succession cools down using the refrigerant. The process seizes heat from space and then releases it into another space. This is the act of a refrigerant. Refrigerants in refrigerating systems (air conditioners) absorb fluid and release heat. Apart from this, Thermodynamic phenomena of phase change are the process also used by refrigerants. This helps the liquid to convert to gas and gas into a liquid. The process of refrigerantstarts in the evaporator component of the system. The refrigerant liquid ...

Indoor air quality (IAQ) is measured with humidity meters and temperature andCO₂ sensors to ensure standards for human comfort indoors. Although human comfort depends on an interaction of multiple variables, optimizing relative humidity, temperature and CO₂ by measuring indoor air quality (IAQ) satisfies the comfort requirements for a wider variety of occupants than optimizing only temperature.

How does humidity affect indoor air quality? Low relative humidity in indoor air results in human discomfort. Headache, irritated eyes, sore throat, and dry skin are all symptoms of a dry indoor environ...

Real-world energy savings obtainable from load vs. lift Variable speed drives (VSDs) can cut a chiller’s annual energy use by up to 30 percent while maintaining operating reliably over a wide range of condition. This is accomplished in two ways:

• At part load when cooling capacity can be reduced, a VSD chiller inherently uses less energy than a constant speed chiller whenever the compressor speed can be reduced to more closely match the load.

• At low-lift conditions, when either tower water temperatures can be reduced or chilled-water-supply temperatures can be increased, up to four times mo...
