We understand that the water source heat pump unit has certain requirements for the water quality of the water source. If the water quality fails to meet the requirements, it will cause harm to the valve, the host and its accessories, especially to the plate heat exchanger used by most heat pump manufacturers, which will affect the operation of the system. However, some treatment methods such as setting up a decontamination device and an electronic descaling instrument can usually be adopted, or several layers of filtering devices are installed in the intake well to reduce the diameter of sand and dust particles contained in the well water, so as to meet the water quality requirements of the unit.

1. When the fire damper is of electric type, 24V is required to be closed. For example, when the fire damper is of 70 ℃, only a response signal is required when the fuse is of active fuse type. Usually, the fire damper is installed behind the static pressure machine of the air conditioner and is normally opened. When a fire breaks out, its 70 fuse is fused and the valve is closed, blocking the air supply from the air conditioner to the fire scene. When the fire damper is closed, the signal is responded to the host.

First, the smoke exhaust port adopts a normally open type air outlet. Normally closed smoke exhaust fire damper is set on the smoke exhaust branch pipe of each smoke prevention zone, and normally open smoke exhaust fire damper is set at the entrance of the smoke exhaust fan. When a fire occurs in a smoke prevention zone, manually or automatically open the normally closed smoke exhaust fire damper on the smoke exhaust branch pipe, and at the same time, chain start the smoke exhaust fan to exhaust smoke. When the smoke temperature exceeds 280°C, automatically close the exhaust valve, at the same time, the chain closes the exhaust fan to stop the exhaust.
