技术领域technical field
本发明涉及一种热回收多联式空调机组的工作方法。The invention relates to a working method of a heat recovery multi-connected air conditioner unit.
背景技术Background technique
常规的制冷机组由压缩机、冷凝器、蒸发器、制冷系统附件以及连接管路等组成一个制冷循环回路，这种机组只能在夏天提供冷气，而其所排出的热量则采用冷却水通过冷却塔而把热量排入大气。为了更好地节约能源、降低运行成本，均希望该机组在制冷的同时还能无偿地提供大量的生活热水来供人们使用。针对上述情况，业界出现了两种热回收方式，一种是以牺牲压缩机的性能为代价的全热回收，为提高出水温度，必须提高制冷系统的冷凝温度，从而导致冷凝压力的提高，压缩机的冷量下降，功率增加，制冷性能系数(EER)降低；另一种是热回收效率较低的部分热回收，为保证热水的出水又不影响压缩机的性能，所能回收利用的只有压缩机排气的显热部分的能量，回收率较低。具有上述二种热回收方式的制冷机组在使用时，同时就会产生热水，没有选择性，使用不方便；然而，当人们不需要热水的时候，就会造成资源的浪费，影响制冷机组的工作效率。A conventional refrigeration unit consists of a compressor, condenser, evaporator, refrigeration system accessories and connecting pipelines to form a refrigeration cycle. This unit can only provide cold air in summer, and the heat it discharges is cooled by cooling water. The tower releases heat into the atmosphere. In order to better save energy and reduce operating costs, it is hoped that the unit can provide a large amount of domestic hot water free of charge for people to use while cooling. In response to the above situation, two heat recovery methods have emerged in the industry. One is the total heat recovery at the expense of the performance of the compressor. The cooling capacity of the machine decreases, the power increases, and the refrigeration performance coefficient (EER) decreases; the other is the partial heat recovery with low heat recovery efficiency. Only the energy of the sensible heat part of the exhaust gas of the compressor has a low recovery rate. When the refrigeration unit with the above two heat recovery methods is in use, it will generate hot water at the same time, which is not selective and inconvenient to use; however, when people do not need hot water, it will cause waste of resources and affect the efficiency of the refrigeration unit. work efficiency.
