TZB-info / Water, sewer / Insulation and Noise Technical requirements for thermal izolciu of heat and hot water according vyhlky. 282/2012 Coll. MOE Date: 03/10/2014 how to make nachoes | Author: Assoc. Ing. Jana perks PhD., Ing. Juraj Januka, PhD., Civil Engineering, STU Bratislava | Reviewer: Ing. Jakub vRNA, Ph.D.
Vyhlka izolciami deals with the distribution of heat and hot water, does not prescribe bag HRBK izolcie against kondenzcii, how to make nachoes ie izolcie for cold water pipes and cooling pipes and ventilation klimatizcie.
From JLA last year is valid vyhlka MoE. 282/2012 Coll., Which have set technical requirements for thermal izolciu of heat and hot water [10]. Vyhlka how to make nachoes izolciami deals with the distribution of heat and hot water, does not prescribe bag HRBK izolcie against kondenzcii, ie izolcie for cold water pipes and cooling how to make nachoes pipes and ventilation how to make nachoes klimatizcie.
Optimal NVRH distribunch continually get the nezaobde without isolating thoroughly how to make nachoes drilled pipe distribution equipment and armatr, the need zapracova Kadej in the project document CII heating and zdravotnotechnickch intalci for realizciu how to make nachoes construction. In addition sprvnej dial materilas quality, which is essential choose according to elu izolcie - ie. either the text or tepelnch strt against how to make nachoes kondenzcii - should be the opinion of necessary HRBK izolcie. Vyhlka dopazkon. 476/2008 Coll. Listen to the efektvnosti of the energy (check on energy efektvnosti) and amending Check for. 555/2005 Coll. Energy hospodrnosti buildings. Vyhlka only deal with izolciami for distribution of heat and hot water, does not prescribe bag HRBK izolcie against kondenzcii, ie izolcie for cold water pipes and cooling pipes and ventilation klimatizcie. 2 Hrbek thermal izolcie
Vyhlka provides minimlnu HRBK thermal izolcie of heat and hot water for the insulation budovch materils thermal conductivity of 0.035 W / (mK) at 0 C according to Table . Table 1. 1 Minimlna Hrbek thermal izolcie of heat and hot water for budovch izolcie with thermal conductivity λ = 0.035 W / (mK) at 0 C [10]. Vntorn pipe diameter or armatry [mm] Minimlna Hrbek izolcie λ = 0.035 W / (mK) [mm] 1 2 20 to 22 23 to 35 30 36 to 3 100 Similarly Hrbek as vntorn pipe diameter of 4 100 100
When rozdeovaoch harvested and heat in places kriovania and spjania how to make nachoes piping and the piping and penetrations in armatrach intalovanch walls and ceilings me minimlna hr Depth izolcie destroyed 50% of the value HRBK izolcie referred to in Tabuk prslunom line [10].
Given values with proposals for the distribution of heat and hot water oceovmi rrkami. If the chosen insulators in materils another thermal conductivity of the pipe or in kind (eg, plastics), must be Hrbek izolcie how to make nachoes prepota according rovncv prlohe. 2 to vyhlke.
How vyplva the tab. 1 HRBK izolcie prescribed for pribline with a 1: 1, ie Hrbek izolcie the pribline also vntornmu pipe diameter, the following is an insulated almost trojnsobn from the outside diameter of the pipe. In practice, how to make nachoes then follows HRBK izolcie Murderers zvyuj requirements for space intalciu pipe. Naprklad of uninsulated rrky DN 32 (42.4 steel 3.25) rise after rrka insulated with a diameter of 35.9 + 2 = 30 mm 95.9 mm. If you side by side; several insulated pipe, NROK space - especially in achtch, drkach and floor - narastaj inlet, e them in viacerch prpadoch The mounting implemented. Problematic is predovetkm intalcia izolovanch pipeline in podlahch with HRBK prescribed for cement screed and vyrovnvajcich layers. how to make nachoes 3 Vpoet HRBK izolcie chosen according vyhlky. 282/2012 Coll.
Vpoet HRBK chosen according izolcie how to make nachoes vyhlky is very practical An nron and Hrbek izolcie with different thermal conductivity values as in Tab . 1 d according to Equation 1 uvedench sweat just zloitm iteranm process using vpotovej techniques: (1)
Substituting into the equation a lot vpotovho using Mathcad program is for elected Material PPR 40 vypotan 6.7 mm external diameter heat izolcie with sinite om thermal conductivity of 0.034 W / mK equivalent to 97 mm (vi.vpoet below), the ERO and after defrost the pipe diameter mono sweat HRBK izolcie, which for tax prpad sufficient straight or vyia than 28.5 mm.
Vpote at the same time nezohaduje temperature Prdící, suits in the pipeline, and even air temperature, in which the pipe Intal. The bag is a difference, and the pipe
