As of late Hundreds of people have been browsing our site searching for Fire Protection Engineering near the Chicago area. This is due primarily due to the following we have built in this types of projects. Nevertheless, a lot of building owners from Lynwood to Winnetka, don’t know that NY-Engineers.Com is also a top contender for anyone searching for HVAC Chicago

The pursuit of power efficient buildings involves cost effective HVAC system design. This will likely include systems for lighting, architectural enclosure, domestic water heating, HVAC, and vertical transportation. The loads for the HVAC systems may come primarily from 5 different places including lighting (cooling), the construction envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load might be a function of either the devices needed in order to introduce it into a space and control contaminant concentration or the number of folks that will use the space. In the majority of climates within the southwestern and eastern regions of the usa, to lower outter air-flow can save energy whenever the outer air is either warm and humid or very cold.
Manipulating the ventilation rate is going to be dependant on occupancy which is called a variety of demand control ventilation. It is a common type of energy conservation plan that is utilized for buildings with occasional or dense occupancy. Having cooling and heating loads dropped as low as possible can be carried out by using an increased performance building envelope, occupancy sensors, and high performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

If you have ever thought about the distinction between a HVAC Engineers vs HVAC Technicians, then continue reading:

Chicago HVAC engineers are definitely the individuals who run setting up of air-con systems both for commercial and residential buildings. They spend plenty of their work in offices doing higher-level organization and planning of installations nonetheless they do also visit job sites every once in awhile.

In comparison, HVAC technicians in Chicago have a tendency to do more of the hands-on work with maintenance and repair. A HVAC technician may deal with an engineer to perform a number of the installation work, particularly for smaller jobs. Generally HVAC techs do considerably more travel and may even spend a lot of time changing filters, identifying leaks, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers might have the chance to make more decisions about systems that are used, and they also would be the individuals who would offer advice about the most sensible refrigerants and which systems would be perfect for a much bigger building. In the industry, there exists some rivalry between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs do require a great expertise in how air-con really works. In recent times huge crowds have been visiting our website searching for HVAC Convention Chicago 2019. With that said, the focus of our company is to become the to go to firm for those searching for a HVAC Chicago and or any of our other services including Architectural Engineering Engineering services.

A Comprehensive Guide to Variable Refrigerant Flow (VRF) Systems

Functions: Heating and Cooling

VRF systems use refrigerant as the heat-carrying medium instead of water, as implied by their name. A pump is controlled by a variable-speed drive to adjust the flow of refrigerant, depending on current load. These plumbing engineering systems are easy to install once contractors get familiarized with them, while also providing flexible operation and a remarkable energy efficiency. Another advantage of VRF systems is their modular design, which makes them a great option for projects that will be built in stages.

The most basic version of a VRF system uses an outside condenser unit that can be used for either heating or cooling. There are two refrigerant lines, one for supply and one for return, and they are shared by various indoor fan-coils. Although this basic VRF configuration does not allow simultaneous heating and cooling for different building areas, there are two ways in which the system can be modified to accomplish this.

Plumbing Engineering: Explaining Different Pipe Systems

Two-Pipe System

When VRF systems only use only one supply line and one return line, it is possible for plumbing engineering professionals to deploy a branch controller for simultaneous heating and cooling of different building areas. The branch controller is installed between the condenser unit and the piping network delivering refrigerant to the indoor fan-coil units.

  • Areas that require cooling are supplied with refrigerant in liquid form (subcooled), and areas that require heating are supplied with refrigerant in gas form (superheated).
  • Basically, the heat extracted from cooled areas is delivered to heated areas, and the condenser only provides the output difference required to balance heating and cooling.
  • Two-pipe VRF systems with a branch controller are recommended when the capacity will be expanded in the future. Since the controller provides hub to which all indoor units connect, there is no need to modify existing refrigerant lines during an expansion.

Simultaneous heating and cooling are only possible in a two-pipe system if a branch controller is deployed. Alternatively, a three-pipe system can be used for buildings with simultaneous heating and cooling needs.

Three-Pipe System

This VRF system configuration uses three lines connected to the condenser unit: one for heating, one for cooling and a common return line. The basic operating principle of a three-pipe VRF system is the following:

  • Instead of using a branch controller to deliver either liquid or gaseous refrigerant, this function is built into the outdoor condenser unit.
  • The three lines (liquid, gas and return) are connected to all indoor fan-coils, and each unit is equipped with a branch selector that switches the supply depending on the specified operating mode – heating or cooling.
  • The return is common for all fan-coils, regardless of their operating mode.

A three-pipe system generally provides a higher heat recovery efficiency than a two-pipe system with a branch controller, but the system provides reduced flexibility for future expansions – the existing refrigerant lines must be modified by someone knowledgeable in plumbing engineering to add more fan-coils.
