Hvac Energy Efficiency
High Voltage Alternating Current (HVAC) is a centralized cooling, heating and ventilating system of a building. The HVAC unit works by drawing in the surrounding air and passing it through a series of refrigerated coils to cool down the air or through heat exchangers and heated by furnace to warm up the air, and then sending it back to its surrounding. Since the HVAC draws in the surrounding air and blows it out again, the air actually goes through a filtration system and hence works as a ventilator for the surrounding air. As a result, these performances require a lot of energy, so HVAC energy efficiency has become essential, and is guided by the HVAC efficiency ratings.
HVAC efficiency rating is determined by the seasonal energy efficiency ratio or SEER that determines the level of efficiency for a centralized air conditioning system such as HVAC. Therefore, the higher the SEER rating, the more energy efficient the HVAC system is. That is because the SEER is calculated using the annual usage divided by the total energy consumed by the system.
Furthermore, there are also some practical operations for the HVAC system to achieve HVAC energy efficiency. First and foremost is by setting the thermostats of the HVAC system between seasons to achieve greater energy efficiency by lowering the thermostat during winter and raising the thermostat during summer. That is because after the HVAC draws in the surrounding air, it will not require so much energy to lower the already cooled air or warmer the already warmed air, and hence achieve energy efficiency. Some of the other method to achieve HVAC energy efficiency includes closely monitoring the water and airflow rates of the system. By doing so, it is possible to achieve minimum energy required to achieve the desired temperature with the HVAC system. Furthermore, by reducing the time usage with an over sized HVAC system that can achieve the desired temperature in a short period of time and then off it before operating again to achieve the desired temperature can also greatly reduce the energy used to operate the system.
Indeed to achieve HVAC energy efficiency, getting a high SEER rating energy efficiency HVAC system can be an option. However, the operating habits on the HVAC system will also play a major role to achieve energy efficiency. Therefore, by knowing how the HVAC system, one can minimize the energy required to run the HVAC to achieve the desired temperature.
It is fairly obvious what the job of a cook will entail, but if you have skills in this area would you consider working on an oil rig to put them to the test? It certainly provides an altogether different environment from where many other cooks work, and yet it is...
