Description: For sale is one new slide type calculator used for calculating R 22 superheat and subcooling. This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate subcooling on a TXV system. The photo shows both sides of the tool. This tool is made of thick durable water resistant paper stock with corner rivets. It fits easily in your shirt pocket at approximately 6.25 inches high by 3.25 inches wide. If you have any questions, feel free to ask and I will answer them to the best of my ability. Large quantities (10 or more) are also available at a discounted price! I also have charts for R- 410a systems, low temp refrigeration and air duct sizing! Check them out in my ebay store while supplies last! Instructions for using Superheat Calculator Side of Slide: 1: Measure indoor dry bulb temperature. 80 degrees 2: Measure outdoor dry bulb temperature. 87 degrees 3: Set Outdoor Temperature and read Required Superheat opposite Indoor Temperature. 16 degrees 4: Measure suction line temperature near suction service valve. 53 degrees 5: Measure suction line pressure at suction service valve. 66 psi 6: Set Suction Line Pressure. Read Required Suction Line Temperature opposite Required Superheat. If the measured suction line temperature does not agree with the required scution line temperature, add refrigerant to lower temperature or remove refrigerant to raise temperature.
