The modular assembly type direct cooling ice rink was born

As we all know, the development of prefabricated buildings is conducive to saving resources and energy, reducing construction pollution, and improving labor productivity and quality and safety levels. The Ministry of Housing and Urban-Rural Development also put forward in the "Thirteenth Five-Year Plan of Action for Prefabricated Buildings" that by 2020, the proportion of prefabricated buildings in the country will account for more than 15% of newly built buildings, of which more than 20% will be promoted in key areas and actively promote More than 15%, and encourage the promotion area to reach more than 10%.

The air skating hall of the Capital Institute of Physical Education is the first modular assembly type direct cooling ice rink. It is located at No. 11 North Third Ring West Road, Haidian District, with a total construction area of 7010 square meters. The skating hall is divided into two venues, south and north. Each venue has an Olympic standard ice rink, with a total ice making area of 3600 square meters.

"Traditional ice rink construction requires coiling, ashing, thermal insulation and waterproofing. It involves a process such as concrete construction, pipeline construction, and insulation layer construction. The cycle is longer. Here, we integrate all materials into one piece In the ice-making board, all that needs to be done on site is industrial installation. "The project leader said.

The size of an ice-making plate is about 5.8 square meters, and 320 ice-making plates can "assemble" an 1800-square-meter ice rink.

"Without welding, concrete pouring, etc., only 15 industrial workers are needed to create a standardized ice rink, and the construction efficiency has increased by at least 30%. More convenient is the future maintenance, each ice-making plate can be Call for repairs easily. "

The person in charge of the project introduced that the main structure of the skating hall also adopts an assembled container solution. 72 containers are shipped to the construction site after being customized and processed by the factory. Workers can complete the assembly by welding and assembling. The construction period is short and more In addition to environmental protection, it can be reused in the future. From start to completion, it took only 130 days to complete the construction task.

Four advantages of modular assembly ice rink

1. Security

High-strength alloy aluminum ice module, high pressure resistance, no leakage in the whole system, stable oil return, using A1 grade refrigerant, direct evaporative ice-making host. The life span is 30 years. Board load 600kg / ㎡. Indoor machine room, easy maintenance. Provide remote monitoring service and duty management.

2. Good quality

The ice temperature in the whole venue is even and consistent, and it is automatically adjusted from -2 ℃ to -9 ℃ according to the needs of the event. It meets the ice standards for each individual event of the ISU.

3. Energy saving

The annual electricity consumption of the standard ice rink is less than 500,000 kWh.

Qibing fast: 10 to 20 hours to complete the ice. The aluminum alloy plate has a high thermal conductivity, which is 92 times that of the concrete floor.

Heat recovery: Under full load, 1.5 tons of 80 ℃ hot water can be produced per hour, which can satisfy the ice pouring on site and hot water for venues.

Fast transition: 35 minutes after turning on the ice melting mode, the aluminum plate is heated from -20 ° C to + 40 ° C, and standard ice rink cleaning takes only 1 hour.

Short construction period: The installation and commissioning of the standard skating rink takes only 20 days.

Cost saving: construction without concrete floor and insulation layer, the ice-making base is shallow, only 15 cm.

4. Environmental protection

Using environmentally friendly refrigerants, non-flammable, non-explosive, colorless, odorless, and ozone-depleting ODP = 0, low global warming potential, various refrigerants can be selected according to user requirements.
