Embodiment Construction

[0023] Because the refrigerating system 200 of the present invention is optimized on the basis of the conventional refrigerating system 100 described in the background section, and in a preferred embodiment of the present invention, no part of the conventional refrigerating system is canceled, Therefore, here, the same or similar components will not be repeated here. The specific improvements can be understood in conjunction with the following descriptions.

[0024] A branch pipeline 202 is installed between the outlet pipeline of the second-stage heat exchanger 106 and the pipeline connected to the mixing chamber, and a valve 204 is installed on the branch pipeline 202, which is called an economical valve in the present invention. When the economical valve 204 is opened, the gas flow can pass through the regenerator 108, condenser 110, water separator 112 and turbine 114 from the outlet of the second-stage heat exchanger 106 and enter the mixing chamber.

Abstract

The invention discloses a refrigeration system for an aircraft. The refrigeration system comprises a first-level heat exchanger, a second-level heat exchanger, a valve, a sensor and a controller, wherein the first-level heat exchanger is used for receiving hot bleed air from a motor; the inlet of the second-level heat exchanger is communicated with the outlet of the first-level heat exchanger; the outlet of the second-level heat exchanger is communicated with the inlet of a mixing cavity; the valve is arranged between the outlet of the second-level heat exchanger and the inlet of the mixing cavity; the sensor is used for at least sensing the temperature of outside air; the controller is used for receiving a parameter of the sensor and comparing the parameter with a stored preset range; and when the parameter is in the preset range, the valve is opened through the controller, and the hot bleed air enters into the mixing cavity after passing through the first-level heat exchanger, the second-level heat exchanger and the valve sequentially. By application of the refrigeration system disclosed by the invention, the energy consumption can be effectively reduced, and the economic performance is improved.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to an aircraft refrigeration system. Background technique [0002] Refrigeration system is the core component of aircraft cabin air conditioning. At present, air circulation refrigeration systems are used in most passenger aircraft, and the three-wheel air circulation refrigeration system is particularly widely used in mainstream mainline passenger aircraft. [0003] like figure 1 As shown, this refrigeration system 100 includes a first stage heat exchanger 102, a compressor 104, a second stage heat exchanger 106, a regenerator 108, a condenser 110, a water separator 112, a turbine 114, a flow control valve 116 , Ram air regulating valve 117, temperature control valve 118, etc. Wherein, one end of the first stage heat exchanger 102 is used to receive the hot bleed air from the flow control valve 116 , and the other end is respectively connected to the intake end of the compressor 104 and...
