Consider also having a hydraulic ram pump (and instructions on how to use, or to build one from scratch, along with sufficient piping to move water....which can be "scavenged" from a home plumbing system) and/or 12V water pumps in storage which may be of use in designing a primitive water distribution system for the home or for crop irrigation (i.e., water can be channeled up to an elevated holding canister).

还要考虑有一个水压撞锤式水泵备有怎样使用的说明书，或从头开始造一个，要有充足的导管取水。。。。。。这可从家庭配管系统中搜寻到）。也可考虑存留一个12伏的电水泵，在为家庭或庄稼灌溉设计原始的水分配系统时，它也许有用处。例如，水可被传输到升高的支持罐中。

Based on dynamic load calculation and the cooling and heating characteristic curve of the practical air/water heat pump residential central air conditioning, this paper calculates hiemal and aestival electric consumption and seasonal efficiency of air/water heat pump residential central air conditioning, and compares its economy with that of separate type room air conditioner .

在动态负荷计算的基础上，按实际运行的空气/水型户式空调机组的制热与制冷特性曲线，计算了该种户式中央空调系统冬夏季耗电量与季节效率HSPF及SEER，并在此基础上与采用分体式空调器方案作了经济性比较。结果表明，在具有典型夏热冬冷气候特点的湖南衡阳地区，住宅建筑空调采用空气/水热泵型户式中央空调系统是可行的

For the aim of saving energy and optimizing control of chilled systems, the performance of VWV systems and characteristics of control systems were analyzed based on the simulation. According to the characteristic of the monitored parameters and controlled variables in VWV systems, three online optimal control strategies were proposed and validated:(1) Optimal strategy for on/off control of chillers according to the ratio of secondary flow rate to primary flow rate.(2) Optimal strategy for the control of secondary pump according to value positions of auto-controlled AHU vales. And (3) Optimal strategy for supply chilled water temperature control of chillers according to valve positions of auto-controlled AHU valves and working status of secondary pump.

为达到节能和优化系统控制的目的，在楼宇空调水系统及其局部控制仿真分析的基础上，针对变流量系统监测点和可调参数较多的特点，提出并验证了3个实时优化控制方案：根据初级和二级冷谋水流量的比率，实时优化多台冷水机组的启／停控制；利用AHU自动控制水阀的阀位信息，实时优化二级水泵的控制；利用AHU自动控制水阀的阀位信息以及二级泵的工作状况，实时优化冷水机组出水温度的控制。
