Abstract

The present invention provides a heat pump unit control method, device, storage medium and heat pump unit. The method includes: a judging step for judging whether the four-way valve is reversing after the four-way valve is powered on in the heating mode Abnormal; the execution step is used to execute the first operation if the four-way valve is judged to be abnormal in the judgment step; wherein, the first operation includes: powering down the four-way valve and executing At least one of increasing the frequency of the compressor to a preset frequency, stopping the operation of the indoor and outdoor fans or the indoor water pump, and adjusting the opening of the throttling device to a preset opening. The solution provided by the invention can increase the pressure difference when the four-way valve is powered on in a short time, and can quickly and effectively realize the normal reversing function of the four-way valve.

Description

Technical field [0001] The invention relates to the field of control, in particular to a heat pump unit control method, device, storage medium and heat pump unit. Background technique [0002] At present, air source heat pump units are widely promoted. The four-way valve is one of the important components of heat pump air conditioners. The heat pump air conditioner realizes the conversion between cooling mode and heating mode through the four-way valve, so as to meet the user's requirements for indoor temperature in different seasons. The four-way valve is a differential pressure-driven valve, which relies on the pressure difference between the two ends of the piston to push the piston to achieve reversal. At present, the reversing control of the four-way valve is generally "direct energization reversing", due to the reliability of the four-way valve and the unstable refrigeration system Due to the influence of other factors, the four-way valve sometimes has abnormal reversal. Ge...
