Selection of Industrial Refrigeration Equipment

Choosing industrial refrigeration equipment for enterprises, primarily necessary to define what tasks you are going to put in front of him and try to take into account all the factors that will continue to affect the performance of the system cooling. Such options may be few, but you need to choose the most optimal.

To correctly determine the choice of refrigeration equipment must always take into account the system parameters such as:

  1. extreme heat
  2. the amount of heat in a time interval,
  3. Hydraulic resistance, as well as pre-agree on the heat dissipation and duplication systems.

As practice shows, in most cases, for a rational use of the equipment necessary to install more than one cooling system, and more. This is because the performance of the equipment at different times can be different: for example, a higher weekdays and weekends – lower. In such cases it is sufficient to install a small, which will increase the wear resistance of the cooling system and save on operating costs.

When choosing a pump to circulate the fluid, you will need to take into account the following factors: the diameter of the pipes, liquid lifting height and its distance from the energy source.

If the result of calculating the cost of refrigeration equipment coincides with the cost of downtime of the equipment, then we can consider the option of picking system spare equipment. In this case the two systems communicate with each other by the control unit, which in the case of an emergency or an unexpected stop of the main equipment will automatically turn spare.

Chiller Purchasing equipment with a powerful electric drive, you should consider that it has a limited number of starts per hour and running at the same time in the most unfavorable mode. Starting currents in this case is increased tenfold, and increases heat power cable is hundreds of times.

In contrast to the rated speed, increasing the current strength affects the torque, which increases at the start of dynamic impact on the shaft, bearings and couplings. Now, having seen the consequences of such a choice, you can imagine how many are able to serve in a similar refrigeration equipment operating conditions.

Surety Bonds 101 – Code for HVAC Contractors

Leave a reply

 

Surety bonds 101 refers to regulate the HVAC contractor follow the rules and regulations for the customers and for the municipality.

Holding it will confirm the contractor was responsible and the fulfillment of its obligations which reduces risk of customers. Bonded HVAC contractor will have extensive knowledge of design, implementation, handling, dispensing, cleaning support and security as per the regulations.

Guarantee agreement may be concluded to ensure the obligations which arise in the future.

Bond 101 is the credit provided surety to the customer, whenever a contractor fails to fulfill offered thins in contract the customer can able to file a claim on the business.

General requirements and regulations to obtain the license will vary state to state, and sometimes it’s not require by the state regulation.

On the basis of notification information the Contractor can apply with formal process, once you have gotten your bond, you will have to submit to the relevant authority to get issue your license for training and exam certificates.

Advantages of Packaged Rooftop Units

  1. Wide range of rooftop HVAC units allows you to adapt too many different situations.
  2. If your requirements have been enlarged or extended, simply you can add few more units.
  3. In a commercial building it gives pleasant impression for any customers who visit.
  4. A smaller amount of area is enough to place rooftop units; other modes of hvac systems not as much.
  5. A packed systems includes integrated control and reduced expense and cost of additional external control technology
  6. Real-time monitoring provides system performance and savings rating
  7. Online tracking allows to maintain comfort between regular and peak hours of operation occupants
  8. Simple trouble shooting checks are enough to maintain the efficiency of roof top hvac units
  9. Life of a roof top units will come along for long period of time.
  10. When it comes to cost it saves much better

General Techniques to save HVAC Operational Costs in Industries

Leave a reply

HVAC systems plays a vital role in industries, and it is a key element which determines the work place comfort, production quality as well as production speed. Moreover in most of industrial manufacturing companies the electric utility of HVAC systems will account for 40% of the total usage.

Here were giving techniques to have control over comfortable working environments utility costs of HVAC systems.

As Seasons Change Temperature Setting

Analyze the temperature data collected last year on various seasons such as spring, summer, autumn and winter and adjusts the heating or cooling in the building.

Lowering set points by just 1°C can potentially reduce your annual heating bill by up to 8%, so adjust to correct temperature required.

Shifting Operations Timings

Try shifting the production schedule, depending upon the local climate will Lower Energy Bills and Improve Comfort. If the outside air is significantly cooler and dryer than the returning air using that will provide some additional free cooling (Night Cooling works the best).

Integrating Lighting Controls with HVAC

Providing an efficient building requires both thermal and visual comfort, and this starts with lighting and HVAC controls. Because through scheduled operated lights will have control over the unwanted temperature increase caused by lights and can able to use only when required.

According to the EPA, the average building waste 30% of its energy due to inadequacies.
