Abstract

The invention provides a refrigerating system. The refrigerating system comprises a compressor (1), an evaporation device and a condensation device; the compressor comprises more than two compressioncavities and further comprises more than one switching compression cavity, more than one air supplement port and more than one air supplement branch (10), wherein the compression cavities are independent from each other, and the air supplement branches (10) are located outside the compressor; the air supplement ports can be connected to at least one of the air supplement branches (10); the air suction ends of the switching compression cavities are connected to the air supplement ports; and the exhaust ends of the switching compression cavities are connected to an exhaust port of the compressor. Compared with an original two-stage or quasi-two-stage air supplement enthalpy increasing system loop, the refrigerating system has the beneficial effects that a technology combining air supplemententhalpy increasing and parallel compression is adopted, air supplement enthalpy increasing can be realized by utilizing the air supplement branches, the mixing loss of air supplement can be effectively reduced, the backflow loss and the flowing resistance loss of air supplement can be reduced, and therefore the air supplement enthalpy increasing effect can be improved, the heating capacity of therefrigerating system at a low temperature can be improved, and the energy efficiency level of the system can be improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a refrigeration system. Background technique [0002] The patent with publication number CN105444453A proposes a dual-temperature refrigeration and heating system realized by a single-stage two-cylinder compressor. By using two cylinders and two connected four-way valves and corresponding different refrigerant circuits, Realize dual evaporating temperature cooling or dual condensing temperature heating, dual-temperature cooling or dual-temperature heating realize cascade cooling or heating, and improve the energy efficiency level of the system. [0003] However, the heating capacity of the dual-temperature system will rapidly decay as the outdoor ambient temperature drops. In order to solve this problem, two-stage or quasi-two-stage compression intermediate air supplementation technology is generally used to increase enthalpy, but there are various degrees of...
