Condensing fan control method and refrigeration apparatus

Abstract

This invention discloses a condenser fan control method and a refrigeration device. The condenser fan control method includes: after the compressor's start / stop state changes, obtaining the actual temperature T of the condenser. LN According to the actual temperature T LN The high and low delay switching of the condenser fan's start / stop state. Changes in the compressor's start / stop state include the compressor switching from off to on and / or from on to off; after the compressor starts, the actual temperature T of the condenser is obtained. LN If the actual temperature T LN Rise to t 开1 The condenser fan delay is h 开 Start; and / or obtain the actual temperature T of the condenser after the compressor stops. LN According to the actual temperature T LN High and low adjustment h 关 The length of the condenser fan delay (h) 关 Power off. This invention reduces noise generated when the refrigeration equipment is turned on and accelerates heat dissipation when the refrigeration equipment is turned off by delaying the switching of the condenser fan's start-up and shutdown states, thereby effectively improving the user experience.
