My colleague and I had a recent discussion about his ongoing project. We focused on figuring out how adding an Energy Recovery Ventilator (ERV) to treat ventilation air impacts the run time of air conditioning equipment. To answer this, we used adicot.com's Psychrometric Chart 2-Condition Calclator and the methodology shown below to compare equipment run times with untreated ventilation air versus ventilation air treated by an ERV. The results showed an impressive 27% reduction in equipment run time due to the ERV implementation. You'll find the details of our approach in the following section. To solve this problem, we assumed the following will be given: Given: Equipment Cooling Capacity [BTU/h] provided by the manufacturer ASHRAE Outside air design temperatures (Dry bulb and wet bulb) [oF] Coil Leaving Air Temperatures (Dry bulb and wet bulb) [oF] provided by the manufacturer Ventilation air volume [cfm] per ASHRAE 62.# or Building Code Procedure: Calculate the Ventilation Air Total Cooling Load [BTU/h] (Psychrometric Chart 2-Condition Calculator) Run time = Ventilation load/Equipment Capacity x 60 min [min] Example: Equipment Cooling Capacity: 2.50 tons or 30,000 BTU/h Outside air temperatures in Boston, MA: 88oF / 72oF Coil Leaving Air Temperatures: 55oF / 54.9oF Ventilation air volume: 100 CFM Calculate the total load of ventilation air using Psychrometric Chart 2-Condition Calculator where: Entering Conditions are outside air design temperatures Exiting Conditions are coil-leaving air temperatures Ventilation Air Total Cooling Load = 5,483 BTU/h Run time =5,483 BTU/h / 30,000 BTU/h x 60 min/hr = 11 minutes/hour to condition the ventilation air Adding an ERV: Replace outside air temperature with the ERV leaving air temperature (100 CFM @ 78 Dry bulb, 68 Wet bulb): Total Load: 4,023 BTU/h Run time: 8 minutes/hour to condition ventilation air The results show the effect of ERV or AC Equipment Run time is significant and that adding an ERV reduces the equipment run time caused by ventilation air by 27%.

This video shows How to use the Cooling Load (Sanity) Check Calculator. You can access all our calc ulators on the HVAC Calculators page. This Cooling Load Sanity Check Calculator is a valuable tool for architects, engineers, building owners, and developers to use in pre-design meetings and during the design phase as a "sanity check" for your load calculation. As a caveat, the calculator is not intended to replace a load calculation. Instead, it gives an insight into the range of what other buildings of the same type have historically installed for refrigera tion, occupancy, and lights and equipment. These estimates do not consider any of the standard inputs used in a load calculation, for example, building materials' efficiencies, geographic location, building orientation, and the number of windows. When using this calculator, consider that as buildings become more efficient and lighting and equipment become more efficient, the watts and tons will trend lower. A quick example of How to use the Cooling Load (Sanity) Check Calculator: as with most of our calculators, you can choose Imperial or Metric units. Let's demonstrate this calculator using Imperial units. We will evaluate a 10,000 SF (929 m^2) office space. The data for this calculator was gathered from various sources , and the output informat ion may look different depending on the Building Type you select. Select Imperial Units from the Units dropdown menu, enter 10,000 SF in the Project Area box, and select Office: One Story from the Building Type dropdown menu. The result is an estimated 29 tons of cooling. You can play around with the building type to gain more information about the range of refrigeration you might expect. Let's select Office: Office Buildings (General). The results now show a capacity of 28-tons to 53-tons. You can discern whether your building will be on the high end or low end of this estimate based on things like orientation, location, and quality of construction.

This article and video provide a demonstration of Adicot's Vapor Pressure Deficit (VPD) Calculator for Indoor Growers and Grow Rooms. This calculator is a useful tool for Indoor Growers setting up Grow Rooms. The user is able to hone in on temperature and humidity values to optimize plant health as well as energy conservation. This Vapor Pressure Deficit (VPD) calculator is used to determine temperature and humidity for indoor grow rooms. I am not a grower, so I cannot advise you what your VPD should be, but here is an excellent article From Cannabis Science and Technology describing VPD at different stages of growth. So let us get right into it. You can choose either imperial or metric units. For this demonstration, I will use imperial units. Begin by entering room conditions of 78 degrees Fahrenheit and 60% relative humidity. When you hover over the Leaf Temperature input box, a note explains that as the leaf grows, more evaporative cooling takes place, so the leaf temperature drops. If you do not know your leaf temperature, a rule of thumb is that you could assume a temperature drop of about 2 degrees Fahrenheit. Following that rule of thumb, we will use a leaf temperature of 76 degrees Fahrenheit. These inputs give a room VPD of 1.31kPa and a leaf VPD of 1.1kPa. The clear benefit of targeting a VPD is healthy, robust plants. Another benefit of targeting VPD is energy savings. Let us try one more scenario. Let us say you are in a hot, humid climate. You can allow the temperature to be set to 82 degrees Fahrenheit and 65% relative humidity and still achieve the same leaf and room VPD values of 1.31kPa and 1.1KPa, respectively.
