How to select the qualified chiller for an Ice skating rink 2022-09-23
Ice sports cannot be separated from ice rinks. With the development of technology, artificial ice rinks are constantly emerging. The design of the artificial ice rink should consider the location conditions of the ice rink, the purpose of the ice rink, and the geographical location of the ice rink. The design of artificial ice rink should pay special attention to the requirements of ice rink structure design and load calculation. How to select the qualified chiller for an Ice skating rink? HSTARS Group will help you to select the best ice rink chiller , because gradually some Hockey players have complained about the conditions of the ice rinks which might arise from humidity, leakage, or wrong ice temperatures. The refrigeration technology underlying ice rinks is in fact the same as in refrigerators and air conditioners.

Ice rink chiller


1. Load calculation of ice rink
The main difference between ice rinks and refrigerators or air conditioners is that the refrigerant doesn’t cool the ice directly. Instead, the refrigerant cools glycol, which is an anti-freeze agent that is pumped through pipes underneath the ice.The load of the ice rink mainly depends on the purpose and structure of the ice rink, the size of the ice rink, the latitude and topography of the ice rink, and the length of the season of use. From the analysis of the cooling load per unit area of the ice rinks that have been built in northern country, below is one of H.Stars project example:

The indoor ice skating rink is about 163~233w/m2.
The outdoor ice skating rink is about 488~512w/m2.
The load of ice rink will decide the capacity of ice skating rink chiller


Load calculation of ice rink


1.Skating surface
2.Chilled concrete slab
3.Insulation
4.Heated concrete
5.Sand and gravel base
6.Ground water drain


The following table are the empirical value of cooling capacity required for ice rink chiller listed in ASHRAE-1994 in the United States:

2. Below are the best characteristics of a qualified ice rink glycol chiller for skating rinks
1. It must adopt a well-known brand compressor with 5:6 screw rotor design, high energy efficiency.
2. The evaporator should independently research and develop and manufactured in strict accordance with national standards to ensure the safety and reliability of the product.
3. The reasonable design of the finned condenser reduces the energy efficiency of the fan and reduces the pressure drop of the refrigerant in the coil while obtaining the maximum heat exchange.
4. Axial fan: dedicated low-energy fan, the motor is waterproof and dustproof; IP54.
5. Mobile design: The customized frame structure of the unit is convenient for customers to hoist and move.
6. Integrated design: heat preservation water tank, ice water pump, valve pipeline are manufactured in the factory, and customers only need to connect the pipeline on site.
7. Control system: Siemens PLC man-machine interface for operation.
8. It adopts heat recovery unit.
9. The unit has cloud service, and the global version is optional.
10. The ice water temperature range of the unit: -20 degrees to -10 degrees.
