On the front of the guide is a sliding chart to calculate back pressure, air temperature and head pressure for specific suction temperatures and condenser temperatures. the pressures of R-410A versus R-22 (see chart on the next page). Refrigerants used to give air conditioning units their cooling qualities have been evolving since modern refrigeration came about. R410A Pressure Enthalpy Chart. The penalties for liquid pressure drop are minimized provided the pressure drop does not exceed 50 PSI for R410A systems. observing that suction pressure drops and discharge pressure rises when the compressor is energized. Some manufacturers even color code the hand valves. *PH 15 SEER Multi-Position Package Heat Pumps with R-410A Refrigerant & Accessories. Diagrams: System Pressure Chart Get a quick look at what an average A/C system looks like, along with the compressor manufacturer and what the specific R-134a requirements are for your car. This guide explains why systems are pressure tested, and how to safely pressure test using nitrogen. For instance, R-410A builds up system pressure on the high-pressure side that is 50 percent greater than R-22, putting overwhelming strain on the compressor, lines and seals. If an electronic controller is used, the system can be locked out after repeated low pressure trips. • R410A has a 60% higher operating pressure than R22 thus requiring a thicker wall copper tube and significantly stronger (R410A) copper fittings. Below the calculator is an approximate chart relationship of temperature to pressure. Outside air vents open. 6 times) greater than R-22. These PH diagrams are available for all the common refrigerant gasses. All of the relevant properties are shown in Fig. is 70 psig. 15, 1993 (Grandfathered Unit) After Nov. AZ-20 (R-410A) pressure is about 60% (1. R-410A systems operate at higher pressures than standard R-22 systems. The gauge will have a pressure reading in pounds per square inch gauge (PSIG) and a R-410 refrigerant saturation temperature measured in degrees Fahrenheit (F). ant Charging Chart. If you had a "head pressure" of 198 PSIG and looked at a temperature/pressure chart, you would see that the saturated temperature is 100 degrees. RED TEK Ultra Tacky Grease; RED TEK HX-10 Grease; RED TEK. Knowing how to construct and interpret a pressure enthalpy (PH chart separates the good technician from the very good service engineer.

Using the touch screen, users can quickly calculate superheat and subcool averages to set a control. When these units were brought out the thickness of the copper tube was increased to safely handle the higher pressure. TECHNICAL R-410A DATA SHEET Features and uses of R-410A R410A is an almost azeotropic mixture composed of R-125 and R-32, it is currently used primarily in new air conditioners that are appearing on the market. Add refrigerant to raise the pres­ sure to match the chart, or remove refrigerant to lower the pressure. A proprietary silver brazing flux shall be used. Here's the chart, however… Superheat is used for charging fixed metering device systems and subcooling is used for TXV or AXV Metering Device systems The difference matters. For R-404A Low Temperature 1 psi; for R-404A and R-22 Medium Temperature 2 psi is used.

On the front of the guide is a sliding chart to calculate back pressure, air temperature and head pressure for specific suction temperatures and condenser temperatures. Honeywell offers a colorful display in which users can select a refrigerant and get all of the data they need to perform their tasks in the field. R410A has a pressure considerably above that of R22, which should tend to reduce system cost. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. Use a pressure conversion chart to change the high side pressure to saturated temperature. For example, 275 psi head pressure on an R-22 system converts to 124F. Can R-421A be "topped off"? Yes. A snubber is a Klixon device that works to dampen out extreme pressure spikes that would otherwise lead to unwanted nuisance tripping. Low GWP Opteon™ refrigerants are designed as alternatives to replace previous refrigerants used for AC, refrigeration, and heat pump applications.

As tubing runs become longer, it is inevitable that the ASHRAE recommendation will be exceeded, at times. Pressure Empalthy Chart. The maximum allowable pressure and either the vessel volume or pipe diameter are then required. observing that suction pressure drops and discharge pressure rises when the compressor is energized. It will illustrate how pressure and temperature measurements from a refrigeration unit may be useful for system analysis. upright R-410A drum to center port of gauge manifold. *PH 15 SEER Multi-Position Package Heat Pumps with R-410A Refrigerant & Accessories. The unit has a chart or table to. This, combined with the fact that the theoretical COP is poorer, has lead to the extensive adoption of R407C as an R22 replacement. Since R-410A allows for higher SEER ratings than an R-22 system by reducing power consumption, the overall impact on global warming of R-410A systems can, in some cases, be lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants. These hoses are label with maximum pressure in PSI or bar. Select a refrigerant to view its boiling point, liquid density and pressure/temperature. We will discuss on this video to R22 gas R410a gas and R32 gas and etcetera so watch this video and to know the pressure we maintain on the. 70 degrees on install date and initial start up. Pressure: Temperature. the pressure and temperature of the refrigerant increase, while the heat content of the refrigerant decreases. AZ-20 (R-410A) pressure is about 60% (1. Suction and discharged pressure are 40% to 70% greater than R-22 and the discharge temperature of R-410A is lower due to its higher vapor heat capacity. Find refrigerant charts including SDS & PT Charts as well as relevant topics about the Clean Air Act and other Section 608 resources. Restricted or capped external equalizer 10. We have italicized and bolded them for your convenience.

Performance tolerance 5% 2. 0; R-134a : 21. If the unit required 10 degrees of subcooling, the thermocouple attached to the liquid line should read 90 degrees (10 degrees “colder” than saturated temperature). How does the P/T chart of R-421A compare to R-22? R-421A has a saturation pressure-temperature dependence that is nearly identical to R-22, with a difference of less than 1% for most of the temperature range of interest. This chart will show you how high the pressures are that you will be working with. Note that R-410 is capable of pressures exceeding 600 psi. This Sporlan training module will demonstrate the proper use of the pressure-temperature pocket card or wall chart. 1 Prefixes The prefix is composed of the letter R (for refrigerant).
