The invention discloses a multifunctional refrigerating module and a refrigerating system comprising the same, and aims to provide a refrigerating module which can realize a plurality of types of cycles and a refrigerating system which can realize a plurality of types of refrigerating temperatures. In the module, a compressor, a first two-way valve, a condenser, a first throttle valve, a fourth two-way valve and an evaporator are returned to an air absorbing end of the compressor to form a single stage compression type refrigerating cycle after being connected in sequence; the compressor, thefirst two-way valve, the condenser, the first throttle valve, a third two-way valve, a heat exchanger and a sixth two-way valve are returned to the air absorbing end of the compressor to form a cascade type high temperature stage refrigerating cycle after being connected in sequence; and the compressor, a second two-way valve, the heat exchanger, a fifth two-way valve, a second throttle valve andthe evaporator are returne
