Do You Know What Is VRV Air-Conditioning System?

The Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.

DAIKIN VRV ADVANTAGE

  • Energy-Saving Operation

    Precise individual control and inverter technology minimize energy consumption to deliver optimum energy savings.

  • Individual Control

    VRV systems enable individual climate control settings for each zone to provide the utmost in comfort to commercial building settings.

  • Adaptable Design

    Modular design of outdoor units and wide selection of indoor units ensure system designs that are ideally suited to the environments where they are installed.

  • Flexible Layout

    In addition to a maximum connection of 64 indoor units to 1 outdoor unit, large allowances for piping length and level difference provide a flexible layout.

ABOUT VRV

When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The name VRV *derives from this technology that we call “variable refrigerant volume.”

  • *VRV is a trademark of Daikin Industries, Ltd.

让你省下60%的电费!原来 ‘冷气’ 就是要这样用!

无论你是学生、白领一族还是蓝领一族,大家都花了至少8个小时在工作上或课业上,到了晚上回家,冲个凉开个冷气坐下来享受一下,绝对是人生一件欢乐事。不过,我们家的冷气耗电量都是非常的庞大。

在马来西亚的市面上有许多的省电仪器,可是又担心效果不好,毕竟花费购买一架省电仪器不便宜,同时也不知道是否合法。既然是这样,倒不如我们学学合法的“旁门左道”,这样开冷气不只是可以省电、省钱、还可以享受哦!

技巧一: 常清洗冷气过滤网,水费比电费便宜 ! 

过多的灰尘布满过滤网的洞口,将会大大的减少换热过慢的速度,并达到冷气的热量无法排除。所以,建议2个星期清洗一次,可以增加通风率哦!

技巧二: 开冷气,关窗口;开窗口,关冷气 
这个是非常简单的道理,如果一间房间的门口或窗口一直开开关管,一切的冷风将会很快的被排出去。导致冷气一直需要发动电能,把房间冷却。这个做法,不只是可以达到快速温度下降的效果而且还可以节省高达 5 – 10%的电源能量哦!

技巧三: 温度越低越爽,不过也考虑到皮包有多厚! 
冷气的功能就是让温度下降。许多的人都喜欢把空调温度定位在大约 15 – 21度之间。越低温度的冷气,消耗的能量就越高。因此,如果室外的温度低的话,可以尝试把室内的空调都调高一些。如果下雨天就避免开冷气。温度越高,耗电量就越低(当然也要适当的温度啦,不然冷气装来干啥?)

技巧四: 阳光就是冷气的克星 


当你开着冷气的时候,请确保阳光没有直射入房间。有日光的冷气房,通常耗电量都会额外多出5%或以上。避免阳光直入,可以拉上你们的窗帘啦 =D

技巧五: 出门前提早关闭冷气
反正都要离开房间,提早关闭冷气不只是可以省钱,同时也可以让自己准时离开房间哦!(因为冷气关闭后你会感觉到热气,通常10分钟内就感觉到效果了)

技巧六: 风扇 + 冷气 = 最佳拍档
别以为开了冷气, 就可以关掉风扇, 就可以省电和省钱,其实你们都想错了!当你们开着冷气的时候再来一把会旋转的风扇,不但可以加快你的房间冷度,还可以减少冷气的耗电量哦!*

技巧七: 配管线可以越短越好 
安装冷气的时候最好是确保配管线的顺畅度。越短的配管线就越低耗电量哦!

技巧八: 把冷气都吹向你的脸吧!
有的人很喜欢把冷气都向上吹,主要是认为能够把室内的温度降低。可是,如果你把冷气都向上吹,屋顶上的热气将会先吸收你的冷风再来冷却房间内的温度。除非你是住在屋顶内,否则请把冷气向下吹吧!

技巧九: 你的冷气机太久了
市面上有许多新的冷气,都有省电的功能。一架太久的冷气不只是会让你的耗电量增加,同时也需要高费用去维修或保养。倒不如直接换一架新的冷气,虽然价格稍微贵一点点,不过长远来说,能够为你达到省电的效果才是王道!

以上的这些省电技巧,通常“冷气佬” 都不会和你们说。为了自己的皮包着想,这些省电的小小步骤, 其实就是非常的不起眼的小行为。至于效果有没有,自己尝试一个月就知道了!

空调贴士 (选购及使用攻略)

如今人们的生活水平提高了,空调成为了很多家庭必备的家用电器。很多人只关心空调是否”好冷爽”,能否给大家带来清凉以及省电,但是却忽略了我们应该如何正确使用空调。今天就为大家介绍购买及使用空调的一些小贴士及攻略。

调使用小贴

  1. 空调使用前 :闲置空调重启需注意

很多人家里有些空调,比如说客房,一般不常开启,客人走后多数能闲置几个月,也没有对空调内部进行清洁,外部进行防尘等方面的处理。马来西亚四季如夏,这样未经清洗的空调再次启用对人体健康和空调本身使用寿命都有着非常大的影响。因此,建议常闲置不用的空调再启动前必须进行清洗。

  1. 空调使用时 :“省电” 有技巧

有不少人认为开启空调等凉快后就关掉,当感觉热时再开启空调,会比较省电。其实这个方法是不对的,您每次重启空调时都会突然提升电耗量,空调寿命也会受影响。开启空调时,把温度设置在适中温度即可,不要太低温。空调在制冷时设定的温度高出摄氏2度,就可节省电量约20%,因此,室内温度一般在摄氏27度至28度间比较适宜。

  1. 空调使用后 : 慎防“空调病”

经常使用空调容易生病,“空调病”一般发生在全封闭式空调环境中,公司及家用都是常见的例子。在家里尽量不要24小时连续开启空调,不要全天候关闭窗户,要常打开窗让这个空调环境进行“换气”,至少一个15分钟,这样人在常使用空调的情况下也不会那么容易生病。

选购攻略

  1. 考虑空调的功能

空调的种类众多,功能多不胜数,我们该怎么判定空调的好坏呢?答案:购买时,选定几个牌子来做对比,有些空调虽然标榜同样的匹数/马力,但从数据上还是能看出它够不够“称”的。而功能方面就是个人需求,这里不予置评。

  1. 考虑放置空调房间情况

空调选购还需提前考虑放置位置及情况。应根据房间的保温程度,楼层,房间高度,房间装修布置,房间内设备散热,人员活动状况等,适量的来考虑空调匹数/马力的大小,在朝阳,通风不好的房间应适当增加机器的功率。如何计算您的空间需要多少功率的冷气机,按我。

  1. 考虑空调的结构

空调选购前,需根据防止空间的情况,如选择墙式机还是天花板挂式机,需要结合不同结构空调的特点和放置的房间情况来选择。

  1. 二手房需换新空调

很多人会觉得,前屋主的空调还可以使用,不需要进行更换,剩下一笔费用。但这个处理方式是错的。我们不建议再次使用前屋主的空调。理由:如果前住户有什么疾病,那么空调便是一个传染工具。因为空调的工作方式,是通过先把室内的空气抽走,在压缩机处理后,再送回房间。对于新住户来说,最好不要让吸附了大量老主人生活气息的空调为自己服务。如果坚持使用,至少进行一次全面清洗。

通过以上介绍的关于空调使用小贴士以及空调选购攻略的内容,大家对于空调使用以及空调的选购都有所了解了,希望我们的内容能够帮助阅读本篇的您更好的选购及使用空调。

Are You Buying The Right Horsepower Air Conditioner For Your Room?

One of the most dominant questions in our mind when we want to purchase an air conditioner is, what is the right air conditioner to use? This question points not to what brand of air conditioner to buy, but rather what is the cooling capacity required.
To understand the selection of air conditioner, we first have to know the definition of cooling capacity.
Cooling capacity for a room is basically the heat load in a room that we have to remove in order to achieve certain room temperature and humidity. For most design, this temperature is 24oC and 55 percent humidity. Heat load is measure in Btu per hour. 1 Btu per hour is equivalent to the heat energy required to increase 1 pound of water by 1oF.
A compressor with 1 horsepower capacity is able to remove approximately 9000 Btu/hr of heat. To make things easier, it is generally taken that 1 horsepower means 9000 Btu/hr cooling capacity, even though there are some brands which give you higher than that, some as high as 10,000 Btu/hr from a 1 horsepower compressor. The higher the Btu, the higher the cooling capacity.
Heat in a room comes from many sources. From outside, heat comes through windows, roof, floor and walls. The more exposure to the heat source, the greater the heat load will be. Therefore, rooms facing east and west have higher heat load than rooms facing north and south. Even the material of the glass and bricks affect the heat gain.
Internally, the heat sources are the number of people and their activities, electrical appliances, lighting, heat stove and fresh air that flow into the room. Of course, the bigger the room is, the higher the cooling capacity is required.
It is not easy to estimate the actual heat load of a room without going through some tedious calculation. You are advised to consult air conditioner contractors before you decide on the equipment. Bring along the plan and measurement of your room and be specific what is the function of the room, is it a bedroom or a living room?
There is however, a rule of thumb that could give you a rough estimation of the required cooling capacity. This can be achieved by doing a simple calculation.

 

The formula to calculate estimated cooling capacity:
Total BTU = A + B
= Btu / Hr
A = (Room Width (Feet) x Room Length (Feet) x 50)
B = (No of People x 500)
Faster way to calculate cooling capacity.
The calculation just now is for bedroom only. For other applications, the factor has to be changed. This rule of thumb calculation is just for estimation purposes. It is advised to reconfirm with your air conditioner contractors again before you place your order.
