Profile

• The refrigeration system of indoor ice skating rink usually adopts two refrigeration methods: direct expansion and indirect cooling. Direct expansion adopts "Hstars" brand condensing unit; indirect cooling adopts "Hstars" brand screw type low-temperature chiller, Glycol is used as a refrigerant to form ice on the rink.
• Brand: H'Stars
• Cooling capacity range: 25KW-169KW
• Applications: Ice Rink, Cooling tunnels, food production companies. 

 Parameters

• Cooling range 76kw-363kw Evaporating temperature low -45°C
• Application area Ice rink, Chemical, cold storage

Type selection of refrigerating mainframe

The hardness of the ice surface determines its hardness. Generally speaking, the hardness of the ice surface at -5 degree can meet the requirements. To meet the requirements of ice temperature -5 C, the ethylene glycol solution in pipe of the ice field is set at -15 C.

At present, “Hstars” brand has both water cooled screw-type low temperature water chiller and air-cooled screw-type low temperature water chiller to be choose, also be used without the standard selection of water pump and expansion water tank. it can work immediately at site after Connect pipe and electricity, It can also increase the heat recovery device, make the hot water at the same time, which will improve the economic efficiency.

Air conditioning professional requirements for civil design

Prevent condensation on the roof or ceiling Common technical measures： 

• The ceiling of the ceiling is made of aluminum sheet metal.
•  Increase the surface temperature of the ceiling or roof.
• Indoor set dehumidification device or air conditioning system

Eliminating ice fog

Use the following technical measures to eliminate ice fog

• Reduce indoor wetness.
• Send air to the ice.
• A dehumidifier or an air-conditioning unit (independent air-conditioning unit with a chiller) is installed in the indoor rink to dehumidify the indoor air and reduce the dew point temperature of the indoor air.
