Refresh your information why we use insulation for hot water pipes in water supply system?

to protect the moist from its pipe

Usually the hot water pump flow rate is sized based on the heat loss generated from the pipe in BTU/Hr loss,

Thus it is not only sized to avoid heat transfer from the pipe but to maintain the flow rate required by the pump at which it is sized.

 

1. Prevent heat loss from the pipes between the water heater and faucets.
2. Save energy and decrease your heating bill.
3. Keep pipes from freezing in the winter.
4. Prevent burns when hot water pipes are exposed.
5. Control condensation, particularly in humid climates with cold water supplies.

To prevent heat loss form the pipe to the atmosphere and can maintain loss of energy.

To avoid heat loss because heat transfered from higher to low and if water temperature is high then heat will transfer towards medium of lower temperature.result heat loss will be more and required more energy to reheat the same ( Incase of circulation system). If it's direct supply then finally will not be received desired temp of fluid.

is consist of one condenser and compressor  with more than one evaporator and indoor units 2-  VRF piping network including distributers  and controls for refrigerant flow 3-  VRF  can serve far indoor up to 200 ft distance between indoor and out door 4- VRF compressor is more powerful 5- VRF over all power consumption is less    

to reduce heat transfer between pipes and atmosphere (save energy)

   

To reduce heat loss in the system. By eliminating the heat loss we increase the efficiency of our installation.

To avoid the flow of heat energy from pipe body surface to air and hence resulting in efficeiency.

 

for heat transfer purpose between external surface and internal liquid
