The invention discloses a refrigerating system of a distribution cabinet. The refrigerating system comprises a compressor, a condenser, a liquid distributor with multiple outlets, multiple three-way valves, multiple evaporators and gas collecting pipes; a refrigerant inlet of the condenser is communicated with a refrigerant outlet of the compressor; an inlet of the liquid distributor is communicated with a refrigerant outlet of the condenser; each three-way valve is provided with a first port, a second port and a third port, the first ports of the three-way valves are communicated with the outlets of the liquid distributor respectively, the three-way valves can be switched to the mode that the first ports are at least communicated with the second ports or the third ports or be switched to the mode that neither the second ports nor the third ports are communicated with the first ports; the second ports and the third ports of the three-way valves are both communicated with the evaporators and communicated with refrigerant inlets of the evaporators; inlets of the gas collecting pipes are communicated with refrigerant outlets of the evaporators, and outlets of the gas collecting pipes are communicated with a refrigerant inlet of the compressor. The refrigerating system of the distribution cabinet can effectively solve the problem that bins cannot be individually controlled.
