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...

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 chill...

Why do you want cheap products?

There was one customer once told me about his opinion:"We buy industrial chiller from China because we know it is not expensive, so there is no reason a Chinese brand offer me high price, I won't accept it." Well, we always think that China are not capable of making top quality products. Honestly, I personally thought the same 3-5 years ago. But in recent years, things has obviously changed. I'm not saying that all Chinese manufacturers just hop into the rank of TOP brand, I am saying that China has a different economy environment than before.  You can easily learn from your Chinese supplier that  cost of materials are rising for the past few months. And why is that? Because Chinese government are being more strict to manufacturers on environmental clauses, which apparently had led quite a few suppliers into shutting down. Those suppliers, in my opinion, are typical Chinese business for the past 10-20 years. They don't have high standard for production pr...
