Double-channel variable-capacity heat exchanger

Abstract

The invention provides a double-channel variable-capacity heat exchanger, and relates to parts or devices or components of heating and refrigerating combined systems or heat pump systems, in particular to a heat exchanger used for a heat pump type heating and cooling combined system. A heat exchanger main body comprises two independent refrigerant tube pass channels, and refrigerants in the two channels exchange heat with heating medium water in a shell pass channel at the same time; a water medium heating cycle is established by the shell pass channel and a hot water circulating pump through a hot water circulating pipeline; a first subsystem and a second subsystem are connected to the two refrigerant tube pass channels through a control valve bank, so that a refrigerant circulating loop which can be controlled dynamically is established; and a heat pump system controls the on-off state of the control valve bank of the double-channel variable-capacity heat exchanger, so that the double-channel variable-capacity mode of the double-channel variable-capacity heat exchanger is achieved, the heat exchange area of a tube pass heat exchanger can be effectively utilized, the requirement for stable force output under a large-load working condition is met accordingly, the overall operating efficiency of a unit is greatly improved, and high-energy-efficiency operation of the heat pump system is achieved.

Description

technical field [0001] The present invention relates to a combined heating and cooling system or a component, device or component of a heat pump system, in particular to a heat exchanger for a heat pump combined cooling and heating system. Background technique [0002] The introduction of the slogan of intensive society construction has promoted a higher degree of functional integration in the building itself, and maximized energy utilization has become a current issue. Today, the requirements of commercial and commercial places are getting higher and higher: the air side needs to control the appropriate temperature, humidity and air cleanliness; the water side water temperature is required to be suitable throughout the year. The traditional method of supplying cold and heat sources separately has obviously caused misplacement of resources in different seasons, and at the same time, the initial investment cost of equipment has also greatly increased. like figure 1 As shown...
