In Table 1, the requirements for the columns “Comfort HPAC” require special attention. Here, the
first formula for calculating allowable charge – m L ho A
= 2.5 5 / 4 – requires information on the
installed height of the unit ( ho ), and generic values for this are provided within the standard:
· 0.6 m for floor location
· 1.8 m for wall mounted
· 1.0 m for window mounted
· 2.2 m for ceiling mounted
The second formula in Table 1 – m = 0.55× A× L – has specific conditions applied to it. This is a
special requirement for non fixed factory sealed single package air conditioners or heat pumps with
a charge size of no greater than 8 m³ × L (approximately 300 g for HC refrigerants). This formula
seems to have finally been accepted for all the standards except IEC 60335-2-40. In addition, when
the appliance is switched on, a fan must operate continuously supplying a minimum airflow as
under normal steady state conditions, e

在表1中，所需经费列“慰安妇HPAC ”需要特别注意。在这里，
首先计算公式允许收费-属邮寄
= 2.5 5月4日-需要提供以下资料
安装高度，单位（何） ，和一般值范围内提供这方面的标准：
0.6米的地面位置
1.8米的壁挂式
1.0米的窗口安装
2.2米的天花板安装
第二个公式在表1 -米= 0.55 ×甲× L -有具体的条件适用于它。这是一个
特殊要求的非密封固定单一封装厂空调或热泵与
收费面积不大于8立方米×升（约300克为慧聪制冷剂） 。此公式
似乎终于被接受的所有国际电工委员会的标准，除60335-2-40 。此外，当
该设备已接通电源，风扇运作必须不断提供最低限度的气流
在正常稳态条件下，即使在压缩机关掉的恒温。
上述两个公式只适用于制冷剂的分子质量大于42
千克/ kmol 。
详细的收费限制在表1需要进一步的评论，因为发生略有不同
在不同的标准。具体到中文378 ： 2000年，人们注意到，在信息
附件C ，它是说， 3号制冷剂不应将其用于人体舒适冷却或加热
直接系统，开放间接系统和开放间接通风系统。这意味着
利用碳氧化合物住宅热泵应用应限于与外部系统
二次回路使用水或其他传热流体，可安全内分发
生活区。然而，它是允许的，以符合标准，如果这些信息
要求被忽视。 （这是支持删除这样的要求在
草案prEN 378 ： 2006 ） 。从表1中，只有栏“ RHPAC ”适用。
