家用中央空调选择方案，请大神支招？

最近购入一套156平米四房两厅的住房，空调准备用中央空调！但是关于中央空调的介绍太多，不知道怎么选了！我现在把我的需求说出来，希望大神能帮忙选择下！预算3-4万，客厅一个出风口、饭厅一个出风口、四个房间各一个出风口。制冷效果没什么要求，关键是制热，我们这边是湖南最南边，到了冬天的时候空调在怎么开都冷脚，但是我没有打算装地暖的打算。希望装个中央空调能稍微改善一下这种情况。还有就是不知道用什么方案比较节能。房子就我跟我老婆儿子住，基本上不存在所有空调都打开这种情况，一般最多可能就开2-3个出风口。牌子的选择不是很多，因为我们这边小城市，只有大金、格力、美的之类的中央空调。希望大家能给出品牌以及型号的的参考。谢谢了

大致看了你的情况说明。从制热、负荷设计，选型等几方面来回答你的问题。

家用中央空调制热：

关于中央空调制热，从人体舒适度感受上体验是不如地暖舒适。因为热空气是上浮的。看几张对比图吧：

负荷计算

1.影响负荷因素

影响负荷的因素有很多，如：建筑结构、房间层高、外墙的朝向，窗户的面积、新风情况、房间内散热设备等。

2.计算负荷需掌握的参数

影响负荷的因素有很多，如：建筑结构、房间层高、外墙的朝向，窗户的面积、新风情况、房间内散热设备等。

在了解以上参数后，就可通过负荷计算软件计算出各个房间的单位负荷值。

3.负荷估算冷指标（夏季温度达26℃）

（此处是按照JGJ134-2010《夏热冬冷地区居住建筑节能设计标准》中规定建筑进行估算）

1：别墅的负荷一般要比住宅的大一些。取经验值的中间值至上限。

2：别墅的顶层负荷要大于中间层或底层，取上限。

3：朝向偏西北的负荷取中间值至上限。

4：对于普通挑空客厅选上限值，如采用大型落地玻璃结构，建议进行负荷计算

5：对于外墙较多，面积较大或玻璃面积较大的，建议做负荷计算。

按以上方式去配置室内机。

关于管路，安装，风口等，一般安装公司都能处理好。

最后，说的是品牌。

我个人在问答中多次提到不论合资还是国产，只要是知名品牌，基本上都能满足消费者的需求。且质量总体都不错。选用品牌根据你的预算和喜好决定。这里就没必要特别强调了。
