High-temperature refrigeration air conditioner and high-temperature refrigeration control method

The invention relates to the technical field of air conditioners, in particular to a high-temperature refrigeration air conditioner and a high-temperature refrigeration control method. The high-temperature refrigeration air conditioner comprises a compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger which are connected to form a refrigeration loop or a heating loop. The high-temperature refrigeration air conditioner further comprises a wind shielding device for shielding the indoor heat exchanger, a driving mechanism connected with the wind shielding device, and a control module for controlling the driving mechanism. A pressure sensor connected with the control module is arranged on a pipeline between the outdoor heat exchanger and the compressor, and the control module adjusts the shielding area, shielded by the wind shielding device, of the indoor heat exchanger through the driving mechanism according to data of the pressure sensor. According to the high-temperature refrigeration air conditioner, it is achieved that pressure can be kept within a proper range during refrigeration in the outdoor high-temperature environment, the problem that an air conditioning system cannot run in severe working conditions due to too high pressure is solved, and the running reliability and comfort in the high-temperature environment are greatly improved.

Energy-saving high-temperature-resistant subway train air conditioning

The invention discloses an energy-saving high-temperature-resistant subway train air conditioning. The energy-saving high-temperature-resistant subway train air conditioning is structurally characterized in that: under the condition of not changing the size of the subway train air conditioning, four scroll compressors, an R134a refrigeration agent, two sets of double-loop evaporators, two sets ofdouble-loop condensers, four expansion valves, four solenoid valves and related refrigeration accessories are adopted; the four scroll compressors are rigidly connected with a base plate; then the four scroll compressors and the base plate are arranged on a bottom plate of the air conditioning through four shock absorber assemblies; and the four scroll compressors are set to be four independent loops, and can be subjected to temperature adjustment according to 25 percent, 50 percent, 75 percent and 100 percent of the load of a coach; and a new ventilation door structure under infinitely variable control is arranged on a new air inlet. The invention has the advantages that: the energy-saving high-temperature-resistant subway train air conditioning has low using cost, and can perform four-gear temperature adjustment, the compressors are protected, the power consumption is reduced, the problem that the subway train air conditioning cannot run at the high temperature of more than 46 DEG Cis solved, new air is adjusted effectively to save energy, and the whole shock absorption effect is good.

Production technology of carbon filament beating-up

The invention relates to a production technology of carbon filament beating-up. The production technology comprises the following steps that 1, PAN protofilaments are divided into an upper layer and a lower layer, namely, the PAN protofilament layer containing singular numbers of the protofilaments and the PAN protofilament layer containing even numbers of the protofilaments according to the singular numbers and even numbers through a beating-up machine heald frame; 2, carbon fiber filaments or a weft storage mechanism with the carbon fiber filaments penetrates through openings of the upper layer and lower layer of the PAN protofilaments to make the carbon fiber filaments and the PAN protofilaments woven together; 3, the upper position and the lower position of the heald frame are exchanged, and then the positions of the upper layer PAN protofilaments and the lower layer PAN protofilaments are exchanged; 4, the carbon fiber filaments penetrate through the opening to be woven together with the PAN protofilaments. According to the production technology of carbon filament beating-up, the carbon fiber filaments and the PAN protofilaments are woven together, the problems that due to the fact that the property of the protofilaments is unstable and operation of equipment is unstable, when partial PAN protofilaments are broken, the PAN protofilaments are scattered in the equipment, or due to the fact that the manufacturing precision of the equipment is insufficient, the PAN protofilaments are overlapped, a fire or even an explosion is caused, and the carbon fiber filaments cannot operate normally are solved, the operability during filament breaking is improved, losses are reduced, and personnel safety is improved.
