Problems solved by technology

[0002] In related technologies, when the air source heat pump equipment is in heating operation, defrosting is generally performed according to the heating operation time, and the defrosting mode is actually to switch the conduction direction of the four-way valve, which is equivalent to controlling the air source heat pump equipment to enter the cooling mode. Therefore, frequent defrosting will seriously affect the heating effect of air source heat pump equipment, affect user experience, and have a greater impact on system pressure, greatly reducing system reliability and equipment service life

Abstract

The invention provides a control method and device for air source heat pump equipment, the air source heat pump equipment and a readable storage medium. The control method comprises the following steps of: obtaining an environment temperature and a first temperature of an evaporator inlet of the air source heat pump equipment; and on the basis of a situation that the environment temperature is greater than a first threshold value and the first temperature meets a pre-defrosting condition, controlling the air source heat pump equipment to regulate an operation parameter. By use of the embodiment of the invention, a pre-defrosting mode is set, so that the air source heat pump equipment can carry out pre-defrosting on an evaporator through the heat of the external environment under a non-stopcondition, so that a phenomenon that when the evaporator is slightly frosts, four-way valve reversing causes the temperature of user side air to be lowered or the temperature of a water tank on a user side to be lowered, and the heat generation quantity and the energy efficiency of the heat pump are low in attenuation can be avoided, in addition, a pressure impact on the system due to four-way valve reversing can be reduced, so that system operation reliability and the service life of the equipment can be improved, and user use experience is improved.
