Two 16-cylinder engines combined generate 4400 horsepower that runs the RH400 and its 14 hydraulic pumps that hold up to 3400 gallons of fluid—enough to fill a small backyard pool—to operate.
两个16气罐引擎一起可提供4400马力的动力，有效维持了RH400及其14个总共能容纳3400加仑液体（这足以填满一个小型家庭泳池）的液压泵正常运转。
Meanwhile, only limited number of research papers [7-10] try to examine combined work of heat consumption in buildings control systems and heat pumps (low grade heat sources).
同时，只有有限数量的研究论文[7 - 10]试图研究相结合的建筑耗热量控制系统和热泵（低品位热源）。
The calculations indicates that the new combined operation and defrosting model can improve economics of heat pumps and stability and comfort of heat pumps' heating in low temperature surroundings.
计算分析表明：采用组合运行除霜模式可以提高热泵运行的经济性、低温环境下热泵机组供热的稳定性和供热舒适度。
