家用中央空调系统是指具有统一的冷热源，并将冷热源输送到所需的房间，我们将这种独立服务于每户家庭的中央空调系统称之为家用中央空调系统。

The central air conditioning system of the household refers to a unified cold and heat source, and the cooling and heat source is transported to the required room. The central air conditioning system, which is independently served in every household, is called the household central air conditioning system.

一、家用空调器

1. Household air conditioners

常见的家用空调器有、分体机、柜机等空调机组。家用空调器一般适用于中等收入以下的家庭。

Common household air conditioners, split machines, cabinet machines and other air conditioning units. Household air conditioners are generally suitable for families with medium income.

二、风冷管道式中央空调

Two. Air cooling pipe type central air conditioning

一拖一风管机

A towing pipe machine

风冷管道式中央空调系统由室外机、室内机和室内管道系统组成。风冷管道式中央空调系统价格较低，空调系统可以设有新风装置，空调设备的管理和维修比较方便。

The air-cooled central air-conditioning system consists of an outdoor unit, an indoor unit and an indoor piping system. The air-cooled central air-conditioning system has low price, and the air conditioning system can be equipped with fresh air installations.

风冷管道式中央空调系统不易调节各个房间的温湿度，并且管道要占用一定的空间，设计时，供回风管的布置将是设计中最为困难的事情，同时，还要注意风系统的分配问题，避免出现送风不均的情况。

The air cooling pipe central air conditioning system is not easy to adjust the temperature and humidity of each room, and the pipe should take up a certain space. In design, the layout of the return air pipe will be the most difficult thing in the design. At the same time, we should pay attention to the distribution of the wind system and avoid the uneven distribution of the air supply.

三、家用多联中央空调

Three. Home multiple central air conditioning

多联机、VRV、氟机

Multi line, VRV, fluorine machine

家用多联中央空调系统是家用空调器的变种，即由一台室外机可以同时连接多台室内机组成。家用多联中央空调系统安装简单方便，可以根据装修情况选择不同形式的室内机，在使用时，业主可以根据自己的要求，随意调节室内温度。

The household multi central air conditioning system is a variant of household air conditioners, that is, an outdoor unit can be connected to several indoor units simultaneously. The household multi - central air-conditioning system is easy to install, and can choose different types of indoor machines according to the decoration conditions. In use, the owners can adjust the indoor temperature at will according to their own requirements.

家用多联中央空调系统初投资较大，需要专业安装队伍。空调系统存在制冷剂泄漏的可能。制冷剂泄露较大时。此外，家用多联中央空调系统不能很好地满足寒冷和严寒地区冬季供热的要求，在冬季，寒冷和严寒地区需要有其它供热方式和供热设备。

The household multi central air conditioning system has a large initial investment and needs a professional installation team. There is a possibility of refrigerant leakage in the air conditioning system. When the refrigerant leaks large. In addition, the household multi - central air conditioning system can not meet the requirements of winter heating in cold and cold areas. In winter, cold and cold areas need other heating methods and heating equipment.

四、家用风冷热泵中央空调

Four. Central air conditioning of air cooling heat pump for household

空气源热泵

Air source heat pump

家用风冷热泵中央空调系统由小型室外风冷机和室内末端系统组成。家用风冷热泵中央空调方式可以单独调节每个房间的温度；可以根据不同房间装修情况，采用不同形式的末端设备（如风机盘管、地暖、毛细管、辐射板、暖气片等)，并灵活制冷或采暖。在寒冷和严寒地区，根据当地实际供暖情况与锅炉、太阳能等热源联动供暖。

The household air-cooled heat pump central air-conditioning system consists of a small outdoor air cooler and an indoor terminal system. The air cooling heat pump central air conditioning system can adjust the temperature of each room separately. According to the conditions of different rooms, different types of terminal equipment (such as fan coil, ground heating, capillary, radiant plate, radiator etc.) can be used, and the refrigeration or heating can be flexible. In cold and cold regions, local heating is combined with heating sources such as boilers and solar energy.

五、家用水冷热泵中央空调

Five. Central air conditioning of water cooling heat pump for household

水/地源热泵

Water / ground source heat pump

家用水冷热泵中央空调系统一般是由水源水系统、热泵空调系统和室内末端系统组成。家用水冷热泵中央空调系统主要特点是冷热源为水，冷热源可以为井水、河水、冷热循环水等。家用水冷热泵中央空调系统设计、安装比较复杂，需要与建筑师和结构师紧密配合。

The household water cooled heat pump central air-conditioning system is generally composed of water source water system, heat pump air conditioning system and indoor terminal system. The main features of the household water cooled heat pump central air-conditioning system are that the cold and heat sources are water, and the cold and heat sources can be well water, river water, cold and hot circulating water and so on. The design and installation of the household water cooled heat pump central air-conditioning system is rather complicated and requires close coordination with architects and structural engineers.

室内系统可以分为两种：

The indoor system can be divided into two kinds:

一种是风管式（“水－风”空调），其与风冷管道式中央空调系统相近；

One is the air duct type ("water air"), which is similar to the air-cooled central air-conditioning system.

另一种是水管式（“水－水”空调），其与家用风冷热泵中央空调系统相近。

The other is the water pipe type (water water) air conditioner, which is similar to the household air-cooled heat pump central air-conditioning system.

六、家用空气源热泵两联供地面辐射冷暖系统

Six, household air source heat pump two for ground heating and cooling system.

家用空气源热泵地面辐射系统在我国也是刚刚崛起的一种新型采暖方式。地板辐射采暖、制冷技术在欧洲一些国家比较成熟，我国一些研究者正在进行怎样利用地板辐射制冷的研究，并且已经取得了一定的进展。

The ground source radiation system of household air source heat pump is a new heating method just emerging in China. The radiant floor heating and refrigeration technology are more mature in some countries in Europe. Some researchers in our country are doing the research on how to use the floor radiation refrigeration, and have made some progress.
