Chiller or Cooling Tower?

Chiller and cooling tower are both cooling equipments, but the working principle is quite different. If we compare them with our daily used home appliances, a chiller is like air conditioner, while a cooling tower is like a fan. You can easily see the difference: air conditioner can bring the temperature lower than ambient, while fan can not. 

In industrial process, you can also easily decide what is suitable for you. If your process requires water temperature lower than the ambient, then only chiller unit can meet the requirement. For example, you need cooling water temperature around 15℃, but your ambient temperature is not lower than 15℃, then cooling tower can not manage this case. We talked about ambient temperature instead of wet bulb temperature, because wet bulb temperature is the most ideal result that a cooling tower can get, in most cases, cooling tower can only cool the water down to ambient temperature. 

Sometimes some customer contact us and inquire about industrial chiller, but they told us they need to water to be around 40℃. We will normally suggest cooling tower for them, after all, the cost of cooling tower is much lower than a chiller unit, especially when the cooling capacity is large. The other important thing is that a chiller unit can not process water temperature higher than 35℃, otherwise it will cause damage. 

Cooling tower is used for cooling large volume high temperature water in most factories, including for hydraulic system cooling for injection moulding machines, cooling water for metal processing, etc. The point is that in those applications, there is no strict requirement for cooling water temperature.

Difference between Screw Chiller and Scroll Chiller

Senho industrial chiller units can be divided into many categories in different ways. We will have air-cooled type chiller and water-cooled type chiller if classify according to cooling types. If classify them by different applications, we can get Laser Chillers, HVAC Chillers, etc. Now we are talking about screw chiller and scroll chiller  of Senho Machinery, which are two categories according to different compressor type. The difference between them is as follow: 1. Senho scroll chiller is from 1HP/1Ton to 60HP/60Ton, while minimum screw chiller is 40HP/40Ton. That's because scroll type compressor and screw type compressor are with different cooling capacity range, the max capacity a single scroll compressor has is 30HP, on the other hand, the minimum capacity of screw compressor is 40HP. 2. Standard Senho screw chiller is with no built-in water tank and water pump, while standard Senho scroll chiller is equipped with both tank and pump. Because for scroll chiller, it is

Install industrial chiller by yourself? Pay attention to these aspects, you will be rewarded.

Although Senho Chiller provides installation guidance service, if you already have some experiences in chiller operation and installation, you can choose to proceed by yourself to save labor cost and time. But first we need to stop thinking that chiller installation is simple enough, that we just need to connect it to electricity and water, it can just work well by itself. Pay attention to a few more details, the chiller will return you better performance and longer service life. Here are the precautions that you need to know before proceed: 1.     Selection of installation location. For air cooled chillers, we need an open space with good ventilation. Make sure there is no barriers or walls within 1m around it, otherwise there will be trouble for air flow and heat dissipation. The point is we need to make sure the heat out from the chiller can be removed outside, instead of circulating within a small space. The distance to block also ensures space for maintenance. If

Different Types of Evaporators in Industrial Chiller

图片
As one of the most important parts in a chiller, the purpose of evaporator is to transfer the cooling energy from cold refrigerant(gas) to water or other coolant. There are three main types of evaporator for  industrial chillers , they are coil type, shell and tube type and plate type. Here we are comparing these three types of evaporators from aspects of  Heat Transfer Efficiency, Requirement for Water Quality, Convenience of Maintenance  and  Space Occupation. 1.     Heat Transfer Efficiency. Heat transfer efficiency is very important for a heat exchanger. Normally, plate type evaporator has the highest efficiency than others, because its more precise structure. Shell and tube type ranks second in this list, while coil type has relevantly the poorest efficiency amongst the three types of evaporators.  Heat efficiency needs to based on heat exchange area, higher efficiency means it can transfer more energy with less heat exchange area. On the other hand, if the effici
