水源热泵中央空调是怎么回事？
What's wrong with water source heat pump central air conditioning?
答：水源热泵中央空调系统是一种从地下水资源中提取热量的高效、节能、环保、再生的供热（冷）系统。
Answer: The water source heat pump central air conditioning system is an efficient, energy-saving, environmentally friendly, and regenerative heating (cooling) system that extracts heat from groundwater resources.

水源热泵是否可以既能制冷，又能制热？
Can water source heat pumps both cool and heat?
答：是的。水源热泵以地下水作为冷、热"源体"，在冬季利用热泵吸收其热量向建筑物供暖，在夏季热泵将吸收到的热量向其排放，实现对建筑物供冷。
Answer: Yes. The water source heat pump uses groundwater as the source of cold and heat. In winter, the heat pump absorbs its heat to provide heating to the building, and in summer, the heat pump releases the absorbed heat to it, achieving cooling for the building.

制冷、制热是否要分开设置水环路？
Should separate water loops be set up for refrigeration and heating?
答：不用。制冷、制热工况共用一套水源水环路和一套用户水环路。通过切换系统阀门即可实现夏季制冷和冬季制热。
Answer: No need. The refrigeration and heating conditions share one set of water source loop and one set of user water loop. By switching the system valves, summer cooling and winter heating can be achieved.

水源热泵是怎样工作的？
How does a water source heat pump work?
答：水源热泵的工作原理与风冷热泵基本相同，都是一个"搬运"能量的过程。为用户供热时，水源热泵从水源中提取低品位热能，通过电能驱动的水源中央空调主机（热泵）"泵"送到高温热源，以满足用户供热需求。为用户供冷时，水源中央空调系统将用户室内的余热通过水源中央空调主机（制冷）转移到水源水中，以满足用户制冷需求。
Answer: The working principle of a water source heat pump is basically the same as that of an air-cooled heat pump, both of which involve the process of "transporting" energy. When providing heat to users, the water source heat pump extracts low-grade heat energy from the water source and pumps it to a high-temperature heat source through the central air conditioning unit (heat pump) driven by electricity to meet the heating needs of users. When providing cooling to users, the water source central air conditioning system transfers the indoor waste heat to the water source through the water source central air conditioning unit (refrigeration) to meet the cooling needs of users.

采用水源热泵，还要设置冷却塔和锅炉？
To use a water source heat pump, do you need to install a cooling tower and boiler?
答：由于地下水（恒温带）水温全年波动不大，一般维持在10~22℃，完全能满足水源热泵机组夏季制冷和冬季制热需求。因此，采用水源热泵，不再需要设置冷却塔和锅炉。
Answer: Due to the small fluctuations in groundwater (constant temperature zone) temperature throughout the year, it is generally maintained at 10-22 ℃, which can fully meet the cooling and heating needs of water source heat pump units in summer and winter. Therefore, using water source heat pumps eliminates the need for cooling towers and boilers.

水源热泵中央空调系统由哪几部分组成？
What are the components of a water source heat pump central air conditioning system?
答：水源热泵中央空调系统由末端(室内空气处理末端等)系统、水源中央空调主机(又称为水源热泵)系统和水源水系统三部分组成。
Answer: The water source heat pump central air conditioning system consists of three parts: the terminal (indoor air treatment terminal, etc.) system, the water source central air conditioning host (also known as the water source heat pump) system, and the water source water system.

用户末端系统包括哪几个部分？
What are the components of the user end system?
答：水源热泵用户（室内末端等）系统由用户侧水管系统、循环水泵、水过滤器、水处理仪、各种末端空气处理设备、膨胀定压设备及相关阀门配件等组成。和常规中央空调末端系统基本相同。
Answer: The water source heat pump user (indoor end, etc.) system consists of user side water pipe system, circulating water pump, water filter, water treatment instrument, various end air treatment equipment, expansion and pressure regulating equipment, and related valve accessories. It is basically the same as the conventional central air conditioning terminal system.
