ACH BTU Calculator

ACH Calculator is a digital HVAC calculator for mobile devices with the Android operating system and is designed as an aid for calculating thermal load of a room or other living space and therefore determining the adequate air conditioner cooling capacity for your home. ACH stands for Air Conditioner Home. The results of needed cooling power and investment and operating costs of air-conditioning systems that are obtained using ACH calculator are only approximate (orientational) values, and depending on the specific situation plan of your rooms the results should not deviate more than 30% from the accurate values. The heat load of the home space is affected by a very large number of factors and their mutual relations, so ACH calculator is trying to unify only the most important factors in order not to confuse the users and still obtain a pretty accurate result for air conditioner cooling power. The best results, ACH calculator will display for smaller homes with areas up to 2000 sqft (185m2), for bigger homes possible error in the results increases with increasing area value of your home. In any case, for obtaining precise data it is necessary to hire a licensed HVAC engineer and make HVAC project.

Air conditioner buying, installing and operating costs are given in relation to the average prices of installation and maintenance of air conditioners in the world and the US, therefore cost results represent a rough but relatively good financial estimate of the cost for most spaces. Keep in mind that the price of the air conditioners and the price of the HVAC technician working hours can be significantly different from country to country and may even vary between cities in the same country.

ACH Calculator is intended mostly for homeowners and HVAC equipment salespeople and HVAC technicians, students, and rookie HVAC engineers, although it can also be used by the experienced HVAC engineers to verify and confirm their experiential knowledge of space thermal load. Using ACH calculator can be a quick and easy way for owners of apartments and houses to get a good assessment of the required air conditioner cooling power and also to get a solid picture of financial costs related to the air conditioner installation and maintenance. Also HVAC dealers, at the request of customers, can quickly and easily make a recommendation for the choice of air conditioner based on calculated cooling power and also give other useful information and guidance regarding the air conditioning costs. Using the ACH calculator, HVAC sellers will make a professional impression on their customers, thus building a reputation for themselves and promote sales. Of course, you should always inform your clients that the precise HVAC results can only be calculated through project development made by a professional and licensed HVAC engineers, especially in the case of larger surface areas (more than 200m2) or special purpose areas (laboratories, hospitals, workshops ...).

ACH Calculator was made by Nathan Gale, a graduate mechanical engineer and HVAC designer and maintenance manager with 15 years of experience in the HVAC field. The author will be grateful to every well-intentioned user who points him to any errors or omissions in the ACH calculator and expresses special gratitude to anyone who suggests the way in which this calculator can be improved to be more valuable and useful in its next version.

ACH计算器是用于与Android操作系统的移动设备的数字HVAC计算器和被设计为用于计算的房间或其他居住空间的热负荷，并且因此确定为您的家庭足够空调器冷却能力的辅助。 ACH代表空调主页。正在使用的ACH计算器获得所需要的制冷功率和空调系统的投资和运营成本的结果只是近似（取向）值，并根据你的房间的具体情况计划的结果不应偏离超过30％准确的数值。家居空间的热负荷是由非常多的因素及其相互关系的影响，所以ACH计算器试图统一只为了不混淆用户，并仍然获得空调相当精确的结果的最重要因素冷却功率。最好的结果，ACH计算器会随着你家的面积值的结果增加，显示小一点的房子与地区高达2000平方英尺（185平方米），为更大的房子可能的错误。在任何情况下，为获得准确的数据，必须聘请有执照的HVAC工程师，使HVAC项目。

空调的购买，安装和运营成本相对于空调机安装在全球和美国的维修均价定，因此成本的结果代表了成本的粗糙，但相对良好的财务估计大部分空间。请记住，在空调的价格和HVAC技术人员工作时间的价格可以从国家显著不同，以国家，甚至可能在同一个国家城市之间变化。

ACH计算器旨在多为房主和暖通设备销售人员和技术人员暖通空调，学生和新秀暖通工程师，但它也可以由经验丰富的暖通工程师可以用来验证并确认其空间的热负荷的经验知识。使用ACH计算器可以为公寓和住宅的所有者获得所需要的空调的良好评价冷却能力，也让相关的空调安装和维护财务费用的固体图片的快速简便的方法。此外HVAC经销商，在客户的要求下，可以快速，方便地对空调的基础上计算出的冷却能力选择的建议，并给予有关空调的成本其他有用的信息和指导。使用ACH计算器，暖通卖家会做一个专业的印象，他们的客户，从而建立自己的声誉，促进销售。当然，你应该总是提醒您的确切HVAC结果只能通过项目的开发由专业和行货暖通工程师们计算，特别是在较大的表面积（200m2以上）的情况下或特殊用途的区域（实验室，医院，车间...）。

ACH计算器是由纳丹·盖尔，拥有15年在暖通空调领域经验的毕业生机械工程师和设计师的暖通空调和维护上司的。笔者会感激每一个善意的用户谁指出他在ACH计算器任何错误或遗漏，并表示特别感谢的人谁提出这种计算器可提高到在其下一个版本更有价值的和有用的方式。
