When the temperature of the steam is higher than the saturation temperature, then the state of the steam is referred to as superheated. Measure temperatures at the Heat Pump DSH in and out? gas - Turn off water heater as well during winter? - Home Improvement Superheated steam is preferred during the transfer of heat from one source to another because it acts as an insulator while saturated steam is required for heat transfer processes. I will watch my utility bill to see if the gas portion of the bill changes. 2. In most of the desuperheaters, the fluid that is used for lowering the temperature of the superheated steam is the same as it that of the vapor. On the other hand, the heat absorbed by the liquid coolant helps it in the evaporation process. If a check valve is present, it must be removed or damage to the desuperheater circulator will occur.

The amount of water required in a desuperheater depends on the amount of superheat or degrees of temperature that need to be lowered and depends on the pressure of the steam header. Usually they turn the DSH pump off when source EWT is below 50F in cooling mode, or when the DSH EWT is less than 25F above the refrigerant temperature. Further, the convolutions that are offered by the coils promote turbulence which also contributes to the increased thermal efficiency. Water injection is done in a device called an attemperator or desuperheater. Ideally.. (before the tech touched anything): Desuperheater coils especially the pack less type has a tube-to-tube design.

There are also cases where the discharge temperature is more than 3 degrees of saturation temperature. We overcame this problem by running the water heater timer two times per day at times just before anticipated hot water usage. Desuperheating is the process of preheating your domestic hot water using discharge gas while in heating mode. The temperature difference between the discharge from the compressor and the refrigerant condensing temperature will give the available amount of superheat. The gas water heater is only a year old so I don't know. Contractor says they tell people to turn off the desuperheater in the middle of Winter, unless it looks like a mild Winter. "Thermostats."
