Abstract

The invention discloses a water system air conditioner comprising a plurality of heat pump units and a controller, each heat pump unit is provided with a water inlet pipe, a water outlet pipe, a water pump and a water flow control valve, the water inlet pipes of the multiple heat pump units are connected in parallel, and the water outlet pipes of the multiple heat pump units are connected in parallel; and the controller is configured to determine the opening degree of the water flow control valve of each heat pump unit in the starting state when the water system air conditioner is turned on or the on-off state of any heat pump unit is changed according to the ratio of the water pump capacity of each heat pump unit in the starting state to the sum of the water pump capacity of all heat pump units in the starting state, so that hydraulic balance of the whole water system air conditioner is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a water system air conditioner. Background technique [0002] Water system air conditioners are widely used in floor heating, with good thermal stability and low operating costs. [0003] In order to save energy and control noise, the water system air conditioner will be used in parallel with multiple heat pump units. The water pump capacity of each heat pump unit is different, and the resistance of the waterway is also different. When multiple heat pump units are running at the same time, the water flow of the machine with a large pump may be large, and the water flow of a machine with a small pump may be too small, and even an alarm for low water flow may occur. [0004] At present, the manual water valve of each heat pump unit is manually adjusted to make the hydraulic power relatively balanced. Because there may be many heat pump units connected in parallel, ...
