Data centers and data center HVAC systems are critical, energy-hungry infrastructures that operate around the clock. They provide computing functions that are vital to the daily operations of top economic, scientific, and technological organizations around the world. The amount of energy consumed by these centers is estimated at 3% of the total worldwide electricity use, with an annual growth rate of 4.4%. Naturally, this has a tremendous economic, environmental, and performance impact that makes the energy efficiency of cooling systems one of the primary concerns for data center designers, ahead of the traditional considerations of availability and security.  This article will discuss the ASHRAE data center standards that correlate with these concerns.
ASHRAE data center standards and accompanying studies also show that the largest energy consumer in a typical data center is the cooling infrastructure (50%), followed by servers and storage devices (26%) . Thus, in order to control costs while meeting the increasing demand for data center facilities, designers must make the cooling infrastructure and its energy efficiency their primary focus; introducing ASHRAE data center standards.Data Center HVAC: Which Standards to Follow?
Until recently, this was a challenging task due to the fact that the industry standards used to assess the energy efficiency of data centers and server facilities were inconsistent. To establish a governing rule for data center HVAC energy efficiency measurements, power usage effectiveness (PUE) was introduced in 2010. However, it served as a performance metric rather than a design standard and still failed to address relevant design components, so the problem remained.New Energy Efficiency Standard ASHRAE 90.4
This led the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), one of the main organizations responsible for developing guidelines for various aspects of building design, to develop a new standard that would be more practical for the data center industry. the devised ASHRAE data center standards, ASHRAE 90.4, has been in development for several years and was published in September of 2016, bringing a much-needed standard to the data center community. According to ASHRAE, this new data center HVAC standard, among other things, “establishes the minimum energy efficiency requirements of data centers for design and construction, for the creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.” 
Data Center Model
Overall, this new ASHRAE 90.4 standard contains recommendations for the design, construction, operation, and maintenance of data centers. This ASHRAE data center standard explicitly addresses the unique energy requirements of data centers as opposed to standard buildings, thus integrating the more critical aspects and risks surrounding the operation of data centers. And unlike the PUE energy efficiency metric, the calculations in ASHRAE 90.4 are based on representative components related to design. Organizations need to calculate efficiencies and losses for different elements of the systems and combine them into a single number, which must be equal to or less than the published maximum figures for each climate zone.
From the traditional to the most innovative, there are several drying solutions for your industrial process. Depending on your needs, the processing time, the product final quality or the efficiency of the process can vary considerably. Here is an overview of the different drying methods used depending on the applications and products.
There are a lot of different drying methods. The most common are sun drying, hot air drying, contact drying, infrared drying, freeze-drying, fluidized bed drying, and dielectric drying.
Depending on the nature of the products to be treated, either foodstuff or industrial material, these methods prove to be more or less adapted.
Hot air drying is the most common drying method as of today. It is simple and effective for sturdy industrial and food products and an inexpensive solution.
However, this process can completely dehydrate the product surface, leading to cracks or heterogeneous results. It can also be a slow process depending on the product and the permissible drying temperature.
Drying by exposure to the sun is the oldest and most economical solution. It is well adapted for traditional fruits and vegetables drying in remote areas, like apricots and tomatoes, although it doesn’t preserve all the product properties and vitamins.
But this method requires a lot of space and time, and offer few process control.
This drying method consists in drying a product by putting it in contact with heated walls. Most of the time the drying happens in rotating drums for a better homogeneity. This technology is mostly used in heavy industry drying processes.
However the direct contact of the product with the hot walls can lead to the denaturation of the dried product, and the process homogeneity is not guaranteed.
Infrared drying evaporate water or solvent at high temperature. It can also be coupled with hot air and is used when the drying effect must be concentrated on the surface of the treated product to also obtain a roasting effect.
This solution is far from ideal for products that should not be exposed to high temperatures.
Freeze-drying process is based on the water sublimation effect in a low temperature and low pressure environment. It is often recommended for the drying of temperature sensitive food products, as it preserve most of the organolpetic properties.
On the other hand, freeze-drying is relatively slow and expensive technology, and is mainly a batch process as it works at low pressure.
This technology consists of mixing air and solid particles so that the whole behaves like a fluid. It is mainly used to dry seeds or grainy materials. This drying method is most of the time really quick.
On the other hand, the treated product is subjected to a high temperature which can denature it.
Last but not least, the drying by microwave and radio frequency is based on the dielectric drying technology. By heating the entire volume of the product simultaneously, it is particularly recommended in applications where homogeneous and gentle drying is required.
This solution is the most adapted for drying heat-sensitive products in the food, industrial and medical field, to preserve all of their properties.

Now a days industries required to club all cooling load and installing central chilling plant to get better effciency. if plant is so large then its very difficult to communicate the all places requirement and modulation of central with individual. Hydropneumatic pump skid with VFD is best option for this type of application. With the help of hydro system system will reduce numer of automation and control with more easy and better saving than other. Central chiller plant pump skid required maintain proper pressure in discharge and getting proper feedback of required in plant by observing discharge header pressure. We recently executed similar kind of project capacity of 5000 Tr centrally located and cattering for 4 differnt large spaces. Total Plant bassed on Hydropneumatic concept, if any hanger reduce load then Hydrophnumatic pump system automaticlly sense pressure and controll as per load changes.
