Copper Radiator And The Characteristics Of Steel Radiator Comparison

Steel radiator and copper-aluminum composite radiator is China's northern heating market in addition to cast iron radiator outside the mainstream heating radiator. We have a comprehensive comparison of steel radiator and copper-aluminum composite radiator, so that designers, construction units, home buyers on these two heating radiator products selection and purchase more rational.

First, the steel radiator and copper and aluminum composite radiator comparison of the scope of application

1. Steel radiator scope

The new national standard GB29039-2012 "steel heating radiator" steel radiator includes steel tube / column radiator, steel tube convection radiator (ie, the previous steel finned tube convection radiator), steel plate type Radiator and bathroom radiator and other categories. The scope and water quality of the steel radiator should meet the following requirements:

① According to the national standard "steel heating radiator" GB29039-2012 Article 1 (scope) provides that steel heating radiator for industrial, civil construction is not higher than 95 ℃ hot water for the heat medium heating system.

② According to the national standard "steel heating radiator" GB29039-2012 Appendix A, steel radiator working heating system should be closed system, non-heating season should be full of water maintenance. Radiator work in the heat medium dissolved oxygen is not greater than 0.1mg / L. Working environment conditions can not meet the above requirements should be the system of water or circulating water for appropriate treatment.

③ steel radiator heating system water quality should be consistent with GB / T29044-2012 "heating and air conditioning system water quality" Article 4.5.1 Table 5 provides that the following table shows the GB in Table 5, the main detection items and requirements, but not Limited to the following detections.

2. Copper-aluminum composite radiator

Copper-aluminum composite radiator is a copper tube and aluminum wing profiles with precision rolling technology made of the end of the heating system cooling components, the water part of the copper tube, the heat part of the alloy aluminum, copper and aluminum composite radiator is copper Waterway radiator. According to China's copper and aluminum composite radiator industry standard JG220-2007 "copper-aluminum composite column airfoil radiator" provides copper-aluminum composite radiator for industrial, civil construction is not higher than 95 ℃ hot water for the heat medium heating system, PH = 7-12, chloride and sulfate were not more than 100mg / L.

It can be seen, copper and aluminum composite radiator a wider range of applications, not subject to heating system oxygen limit, and steel radiator work heat medium dissolved oxygen is not greater than 0.1mg / L.

Second, the steel heating radiator and copper and aluminum composite radiator life comparison

China is now promoting the production of copper-aluminum composite column wing radiator, in the high alkaline water quality conditions, if the annual corrosion rate by 0.005mm / year analysis, can have 50 years of corrosion resistance, in this condition leave sufficient room , But also to ensure that the radiator life of more than 30 years.

Steel radiator if to meet the national standard "heating air conditioning system water quality" requirements of the use of heating water, the service life of more than 20 years. If the dissolved oxygen in the water is excessive and the non-heating period can not be covered with water, it may reduce the life of the steel radiator due to oxygen corrosion.

Comparison of Heat Dissipation Performance of Steel Radiator and Copper - Aluminum Composite Radiator

In general, the steel radiator and copper-aluminum composite radiator cooling is very efficient, is our country to promote the new radiator. Copper and aluminum composite radiator metal heat intensity is higher than the steel radiator; steel radiator water capacity is greater than copper and aluminum composite radiator, hot slowly, cool also slow, professional known as hot inertia. Copper and aluminum composite radiator heating up quickly, more suitable for intermittent heating, once the implementation of central heating heat metering, more advantages.

Fourth, steel heating radiator and copper and aluminum composite radiator decorative comparison

Steel radiator hard and straight, with masculine beauty, can be high energy low; copper and aluminum composite radiator copper outside the aluminum, relatively soft, relatively easy to bump deformation, but also high energy low. Both surfaces are very smooth and bright.

Fifth, steel and copper and aluminum composite heating radiator price comparison

Copper and aluminum composite radiator heat price slightly higher than the steel radiator, steel radiator in the steel finned tube convection radiator is the current low price of a radiator.
