Control method for multiple air source heat pump units and air source heat pump system

Abstract

The invention discloses a control method for multiple air source heat pump units and an air source heat pump system.The air source heat pump system comprises the multiple air source heat pump units, each air source heat pump unit comprises a machine cabinet, a compressor, a condensation box, a fin evaporator and a fan are installed in the machine cabinet, a tap water tank is arranged on the right side of each air source heat pump unit, and a water outlet is formed in the right side of the corresponding air source heat pump unit. A heat preservation water tank is arranged on the front side of the tap water tank, a control cabinet is arranged on the front side of the air source heat pump unit, and a controller is arranged in the control cabinet. The air source heat pump system has the beneficial effects that the controller can adjust and control the air source heat pump units according to the hot water demanded quantity in different time periods, the situation that multiple air source heat pump units operate at the same time in the time period with the small hot water demanded quantity is avoided, and therefore energy waste is reduced, and the hot water supply effect is improved.

Description

technical field [0001] The invention relates to a control method of multiple air source heat pump units and an air source heat pump system, in particular to a control method of multiple air source heat pump units and an air source heat pump system, belonging to the technical field of air source heat pumps. Background technique [0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It has the advantages of safety, energy saving and high heating efficiency. [0003] When the existing air source heat pump units are in use, multiple air source heat pump units are usually operated simultaneously for heating, and cannot be adjusted and controlled according to the water supply demand in different time periods, resulting in less demand for hot water in the time period There are still multiple sets of air source heat pump units running for heating, resulting in waste of resource...

[0003] When the existing air source heat pump units are in use, multiple air source heat pump units are usually operated simultaneously for heating, and cannot be adjusted and controlled according to the water supply demand in different time periods, resulting in less demand for hot water in the time period There are still multiple sets of air source heat pump units running for heating, resulting in waste of resources. At the same time, too much hot water inside the water tank will gradually cool down because it cannot be used in time, which will cause waste of hot water. Therefore, we propose a multi- A control method of an air source heat pump unit and an air source heat pump system
