Parallel Chiller System
Chilled water is circulated by the chilled water or primary pump through both chillers to the load and back to the chillers. The chilled water loop can be either constant flow or variable flow. Variable flow systems increase the complexity but offer significant pump work savings. They also resolve the issue about chiller sequencing that occurs with parallel chillers, constant flow. To provide some redundancy in the HVAC design, most designers will require two or more chillers. Multiple chillers also offer the opportunity to improve on overall system part load performance and reduce energy consumption. Parallel chiller plants are straightforward to design and are easily modified for variable primary flow.
空气处理机组 (AHU)
An air handling unit (AHU) is a device that is used to condition and circulate air in a heating, ventilation, and air conditioning (HVAC) system. AHUs are typically located within the building that they serve, and are responsible for cleaning, heating, cooling, and circulating the air within the building.
Booster Pump
A booster pump is a type of pump that is used to increase the pressure of a liquid or gas. This type of pump is commonly used in water systems, such as in municipal water supply systems or in irrigation systems, to increase the pressure of the water so that it can be transported over long distances or through small pipes. Booster pumps can also be used in other systems, such as air conditioning systems or fuel systems, to increase the pressure of the fluid being transported.
Best HVAC Systems
There are many different types of HVAC systems available, each with their own advantages and disadvantages. Some of the most common and best HVAC systems include split systems, packaged systems, variable refrigerant flow systems, geothermal systems, ductless mini-split systems, boiler systems, radiant heating systems, heat recovery ventilation systems, chilled beam systems, and evaporative cooling systems. The choice of the best system will depend on the specific needs of the building and its occupants, as well as the climate and local building codes.
制冷剂管道 - 第 2 部分
In this post, we will be continuing our comprehensive training on how to size refrigerant piping. We will cover all the important aspects of this process, including determining the pipe size, pressure drop, and other factors. We will also discuss topics such as sizing refrigerant lines, equivalent length for refrigerant lines, and how to determine equivalent length. With this training, you will have the knowledge and confidence to size refrigerant piping accurately and correctly in any situation.

Blast Chiller: Everything You Need to Know
Blast chillers are commercial-grade appliances that rapidly reduce the temperature of food. They are used to chill food from the “danger zone” (between 40 and 140 degrees Fahrenheit) to below 38 degrees Fahrenheit within 90 minutes. This is the temperature at which bacteria growth is slowed significantly. Blast chilling offers a number of benefits, including improved food quality, increased food safety, reduced food waste, and increased productivity. Blast chillers can be used to chill a wide variety of foods, including meats, poultry, seafood, fruits, vegetables, and prepared foods.
Accumulator Capacity Calculator
There are two main types of hydraulic accumulators: bladder accumulators and diaphragm accumulators. Both types work on the same basic principle, but they use different methods to separate the hydraulic fluid from the gas. Hydraulic accumulators are an important component of many hydraulic systems. They provide a variety of benefits, such as improved performance, increased reliability, and reduced maintenance costs.

HVAC Control Diagrams
In this blog post, we will introduce some of the most common HVAC control diagrams. We will also provide a brief explanation of each diagram and how its components work together. HVAC control diagrams are essential tools for designing, installing, and maintaining HVAC systems. They provide a visual representation of the system’s components, how they are interconnected, and how they are controlled. This information can be used to troubleshoot problems, optimize performance, and make informed decisions about system upgrades.
