Objective
HCL team has been regularly tracking the HVAC industry for some time. This white paper lists key findings with respect to trends observed and challenges faced by HVAC industry. This is followed by sections on how HCL’s inhouse developed solution IoTF can effectively meet some of these challenges.
HVAC Industry: Trends, Challenges and market drivers:
After tracking the HCL domain experts and business managers have been actively tracking the HVAC industry. Some of their key findings from the recent analysis are listed below:
a) Increased focus on energy conservation and demand prediction: Since prerequisite for any effective management is measurement, a high emphasis is observed on measuring and reporting of energy consumption at an increasingly granular level. Increased focus on the energy utilization is also due to the fact that the energy consumption level in the HVAC appliances is comparatively higher.
b) Slow Economic Recovery resulting in demand moderation of HVAC systems and leading to greater emphasis on energy savings: Global economic recovery has been sluggish especially in the US and Europe regions. This coupled with reduced incomes and high energy bills have impacted the overall demand for HVAC systems.
c) Greater shift towards smart grids, smart metering and building automation: Smart grids helps in intelligent distribution resulting in minimal losses whereas measurement and reporting of consumption in real time is achieved by smart meters.
d) Cost reduction via preventive maintenance and remote diagnostics: HVAC systems are among the largest consumers of energy, indicating that these systems can be source of good savings if the overall performance is increased and the faults are detected on time. Cost saving...

According to the National Bureau of Economic Research, DST increases overall energy consumption by “approximately 1 percent” (Kotchen) and rises to 2-4 percent in the fall. The use of air conditioning, television, lighting, and other appliances causes the residential energy demand to

Refrigeration, the production of cold, is an essential practice for present-day living. It is used in a many place like the processing and preservation of food, conditioning of air for comfort, manufacture of chemicals and other materials, cooling of concrete, medical applications etc. Refrigeration is defined as the science of maintaining the temperature of a particular space lower than its surrounding space. Refrigeration and air conditioning involves various processes such as compression, expansion, cooling, heating, humidification, de-humidification, air purification, air distribution etc. In all these processes, there is an exchange of mass, momentum and energy. All these exchanges are subject to certain fundamental laws. Hence to understand and analyses the refrigeration and air conditioning systems, a basic knowledge of the laws of thermodynamics, fluid mechanics and heat transfer is essential.
The most popular smart homes are Amazon’s Amazon Echo and Google’ Google Home. Both are able to complete many different tasks including: turning in lights, setting alarms, creating or adding to lists, and answering random questions. Some people will refuse to own one of these smart home devices because they feel like the device is always listening to them even if the creators say the device will only listen if the trigger words are said. Smart homes are becoming more and more popular leading to home automation becoming more and more common. Now that almost any aspect of your house that uses electricity can be controlled from the smart home, people have become dependant on the smart home to perform tasks. For example turning on lights, adjusting the thermostat, turning on coffee pots, and even unlocking doors. If the smart home and the smart lights on a ceiling fan become disconnected, the the owner is left to sit in the dark until they reconnect. Having a smart home control your house can cause major problems if there is a

In this paper over natural refrigerant I will be covering the pros and cons of natural refrigerant in light commercial and residential applications. There are many natural substances in this world that can be used to help or decrease the efficiency of a heating ventilation air conditioning system. Some of these substances are water, air, ammonia, and hydrocarbons. All these substances are natural that come from the earth we live on. Over the course of this paper I will be covering the pros and cons of swamp coolers, geo thermal heating and cooling units and how these natural substances can help and or decrease how your heating and cooling unit performs.
We have all heard predictions of Smart homes that interact with Smart Cars to adjust the temperature settings and turn on lights based on the time we come home to refrigerators that can auto restock the groceries by ordering online. A world with ubiquitous Internet connectivity that will totally transform the way we live, work and play will no longer be the stuff of Science fiction in a decade or two. Internet of Things (IoT) that refers to the interconnection of billions of devices within the existing Internet infrastructure is expected to bring automation in all sorts of fields. The advances in Cognitive computing and big data analytics will change the way we deal with the complex problems of the world. Opinions of the over 3000 internet
Humanity is threatened by the overwhelming growth of science and technology. People are expanding their knowledge through observation and experiment, oblivious to the consequences that result from improper motive. Isaac Asimov—author of The Life and Times of Multivac—uses the science of numbers, or mathematics, as a solution to the fear that arises in a world controlled by a human-like machine. What human beings are afraid of is losing the very word that separates them from everything else in the world—human, and they will do whatever they can to keep that title to themselves.
Most people do not have the HVAC repair experience to know where the system failure might
The lodging industry has seen improvement since the economic downturn of late 2007. There are factors beyond the industries control that could stifle growth in the industry, including but not limited to the still weak global economy and governmental breakdown. Since 2010, the industry has seen steady growth in average daily room rate (ADR), revenue per available room (RevPAR), revenue and net income. The have either reached or almost reached pre-downturn (2007) rates. Room construction in much of the United States has also started to rise again but at a slower rate than the financial indicators.
Buildings and the appliances alone account for 40 percent of America 's energy use and a third of our global warming emissions (NRDC). New buildings will need to meet new energy-efficiency standards that maximize energy savings and existing homes and commercial spaces can be improved to save energy through weatherizing and installing energy efficient heating, cooling and lighting systems. Ultimately, this will not only be energy efficient but also cost effective as well. In the bigger picture, retrofitting just 1 out of every 5 homes would avoid the need to build 13 mid-sized power plants every year. Retrofitting every house in the country would cut as much global warming pollution as taking a half a million cars off the road – and would save more oil and gas than we could extract from drilling in our coastal waters (NRDC). In the long run, creating more efficient communities through homes and buildings, we could cut back on the global warming issues we are dealing
Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.
