Abstract

The invention discloses a heat supplying function and air conditioning function switching device of a waterway switching heat pump system, relates to a switching device of a heat pump system and aims to solve the problems that when the heat supplying and air conditioning functions of the heat pump system are switched by depending on starting and stopping of the conventional waterway valve group, valves are complexly operated, and leakage cannot be found. According to a scheme 1, a first connection pipe, a second connection pipe, a third connection pipe, and a fourth connection pipe are parallelly arranged on the same plane, operation directions of valves on the first connection pipe and the third connection pipe are the same, operation directions of valves on the second connection pipe and the fourth connection pipe are the same, four valves which are arranged on the upper part and positioned on the same horizontal straight line are respectively connected with one valve shaft; four valves which are arranged on the lower part and positioned on the same horizontal straight line are respectively connected with the other valve shaft; and a hand wheel is arranged at the end of each valve shaft. According to a scheme 3, a first water storage box and a second water storage box are parallelly arranged longitudinally, and a first connection pipe, a second connection pipe, a third connection pipe, and a fourth connection pipe are arranged in a square mode. The heat supplying function and air conditioning function switching device is applied to a water source heat pump system.

Description

technical field [0001] The invention relates to a switching device for a heat pump system, in particular to a switching device for heating and air conditioning functions of a waterway switching heat pump system. Background technique [0002] There are two main forms for the heat pump system to realize the function switching of heating in winter and air conditioning in summer: one is the unit-side switching mode, that is, the function switching is realized by reversing the flow direction of the refrigerant by relying on the four-way reversing valve in the heat pump unit; The other is the waterway switching mode, that is, outside the heat pump unit, relying on different opening and closing combinations of at least eight valves, the function switching is realized by reversing the flow direction of the low-level heat source water and the end circulating water. At present, the waterway switching mode of the heat pump system is more widely used, but the waterway switching mode sti...
