Refrigerant R12, also known as dichlorodifluoromethane, and R11, also known as trichlorofluoromethane, are chlorofluorocarbons (CFCs) that were commonly used as refrigerants in air conditioning and refrigeration systems. However, due to their harmful impact on the ozone layer, their production and use have been phased out under the Montreal Protocol. These refrigerants have been replaced by more environmentally friendly alternatives such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). **

Cold spray R12/R11 refers to a refrigerant blend used in older air conditioning and refrigeration systems. R12 is a chlorofluorocarbon (CFC) and R11 is a chloroflujson (HCFC), both of which have been phased out due to their harmful impact on the ozone layer. Cold spray R12/R11 is used as a cooling agent in these systems, but its use has been largely discontinued in favor of more environmentally friendly alternatives. **

No, you should not fill an R12 refrigerator with R600a. R12 and R600a are different types of refrigerants with different properties and operating pressures. Using the wrong refrigerant can damage the refrigerator and pose a safety risk. It is important to always use the correct type of refrigerant specified by the manufacturer for your specific refrigerator model. If you need to recharge your refrigerator, consult a professional technician to ensure the proper refrigerant is used. **

The storage charging pump of the Wolf R12 heating control may not be turning off anymore due to a malfunction in the pump itself or a problem with the control unit. It could be caused by a faulty pump motor, a stuck relay, or a malfunctioning temperature sensor. Additionally, there may be an issue with the control unit not receiving the signal to turn off the pump. It is important to troubleshoot and diagnose the specific cause of the issue in order to properly address and fix the problem. **

The amount of insulation required for a facade renovation depends on various factors such as the climate, building codes, and the existing condition of the building. In general, the insulation should be sufficient to meet the energy efficiency requirements of the building and to improve its thermal performance. It is important to consult with a professional architect or engineer to determine the specific insulation needs for a facade renovation project. **

The roofing underlayment serves as a secondary layer of protection against water infiltration and helps to prevent leaks in the roof. It also provides an additional barrier against wind-driven rain and snow. In terms of insulation, the underlayment can help to improve the overall energy efficiency of the roof by reducing heat loss and preventing drafts. Additionally, it can provide a smooth surface for the installation of the final roofing material, such as shingles or tiles. **

When renovating a roof for thermal insulation, it is recommended to consider adding insulation materials such as fiberglass, cellulose, or foam board. These materials can help reduce heat loss and improve energy efficiency. Additionally, sealing any gaps or cracks in the roof structure can prevent air leakage and further improve insulation. Lastly, installing a reflective roof coating can help reduce heat absorption and keep the interior of the building cooler. **
