摘要： A heat pump system and a defrosting control method therefor are provided. The defrosting control method comprises: in S100, initializing a first default parameter TM n and a second default parameter TN n in a preset defrosting interval indicatrix X when a heat pump system runs, wherein the preset defrosting interval indicatrix X=T 1 /TM n +T 2 /TN n , T 1 represents a running time of the heat pump system when an outdoor temperature is greater than or equal to an outdoor temperature preset value, T 2 represents a running time of the heat pump system when the outdoor temperature is less than the outdoor temperature preset value, and n represents the number of executed defrosting cycles; in S200, executing the defrosting cycle when the preset defrosting interval indicatrix X is greater than or equal to a preset constant value, and terminating the defrosting cycle after a defrosting cycle exit condition is met; in S300, obtaining an actual time spent on the defrosting cycle; in S400, comparing the actual time spent on the defrosting cycle with an expected defrosting time, and adjusting the first default parameter and the second default parameter when the actual defrosting time deviates from the expected defrosting time; and in S500, repeating steps S200 to S400. The heat pump system and the defrosting control method therefor according to this application can adjust a defrosting interval according to an actual application situation and achieve a balance between unit performance and comfort degree of customers.

摘要： A ventilator (100) having a functionality to defrost a ventilator core (150) includes two sets of ports, one set used for coupling of the ventilator with ducting and other used for redirecting indoor air flowing along a first flowpath (116) through the recovery core to a second flowpath (118) normally used for outdoor air. A re-circulator (300) is removably fixed between an inlet for outdoor air and an outlet for indoor air of the set of ports not coupled to the ducting. A pair of dampers (164, 166), operated by a single motor (160), allow the ventilator to be operated in a mode that enables redirection of the indoor air from the first flowpath to the second flowpath, simultaneously blocking inflow of the outdoor air.

摘要： The present disclosure relates to the technical field of multi-split control, and provides a defrost control method for a multi-split system, and the system. The method comprises: under the condition that the multi-split system satisfies a defrost condition, determining whether the heat absorption and defrosting capability of a started and operated refrigeration indoor unit is greater than or equal to a preset value; and under the condition that the heat absorption and defrosting capability of the started and operated refrigeration indoor unit is greater than or equal to a preset value, controlling an outdoor unit heat exchanger to be switched from an evaporator to a condenser, so that a refrigerant recovers the heat absorbed by the refrigeration indoor unit, provides the heat for the outdoor unit heat exchanger for defrosting, and provides the heat for a heating indoor unit heat exchanger for heating. Therefore, during the defrosting of an outdoor unit, the heating indoor unit heat exchanger serves as a condenser, so that a large temperature fluctuation of a heated room where the heating indoor unit is located can be avoided, and the multi-split system can perform defrosting on the outdoor unit heat exchanger on the basis that there is no large temperature fluctuation of the heated room where the heating indoor unit is located.
