Embodiment 1

[0035] The air conditioner of the present invention is an integrated DC inverter air conditioner, and the cooling capacity and heating capacity of the air conditioner vary with the change of the working frequency. The air conditioner of the present invention is provided with a direct-current working power supply by a storage battery, the design working time of the storage battery is 5 hours, the working voltage is DC24V, and the power of the generator is more than 1000W. see figure 1 , The air conditioner for special vehicles is 1031mm high, 744mm wide, and 230mm thick. An evaporator and an evaporating fan 13 are arranged in the evaporation chamber, and electrical components such as the main control board 8, the power control board 7, the variable frequency drive board 5, etc. are placed in the electric room. A compressor, a condenser, and a condensation blower fan 33 are arranged in the condensation chamber. The capillary or other throttling elements connect the condenser a...

Embodiment 2

[0041] In the integrated air conditioner of the present invention, the compressor can be an AC variable frequency air conditioner compressor, and the compressor is in a continuous operating state. By adjusting the rotation speed of the compressor to adjust the refrigeration capacity, it is possible to avoid the problems caused by the intermittent start and stop of the compressor. power consumption. When using AC frequency conversion control, the compressor control electrical circuit includes the main drive IC, IPM power module and peripheral control circuits. The main drive IC is set in the electrical room of the air conditioner, and its main function is to complete various calculations, generate SPWM waveforms, realize the control of the V / F curve of the compressor and provide various protections. The IPM power module and its peripheral control circuit are used to complete the inverter process from high-voltage direct current to alternating current, so as to control the opera...

Embodiment 3

[0043] In the integrated air conditioner of the present invention, the compressor can be a fixed-frequency air conditioner compressor, and soft start control is added at the same time. see Figure 5 The electrical control system of the air conditioner consists of load units such as a function control board 66, a power control board 63, a soft start board 62, an input module 67 electrically connected to the above-mentioned control boards, an evaporating fan, a condensing fan, and a fixed-frequency compressor 61. The function control board 66 communicates with the power control board 63. The storage battery 65 provides 24V power to the power control board. see Figure 6 , The soft start board uses the thyristor N2 as a voltage regulator, and connects it between the power supply and the motor stator to control the motor to start. When using the soft start board to start the compressor, the conduction angle of the thyristor gradually increases, the output voltage gradually incre...

Abstract

The invention discloses an air-conditioner which comprises a shell, a refrigerating system comprising a compressor, an evaporator, a capillary tube, a condenser and a four-way valve, and an electrical control system, wherein a storage battery is used to provide direct current power supply to the air-conditioner; an evaporation chamber is arranged on the upper part of the shell; a condensation chamber is arranged on the lower part of the shell; the evaporator is arranged in the evaporation chamber; the condenser and the compressor are arranged in the condensation chamber; an evaporation fan is arranged in the evaporation chamber; a condensation fan is arranged in the condensation chamber; the evaporation fan is a cross-flow fan; and the condensation fan is an axial-flow fan. The air-conditioner is an integral type air conditioner with compact structure and convenience in mounting, and has the great advantages of cost and difficulty in leakage compared with a detachable air conditioner. The power is provided by the storage battery; the operation of the compressor is not limited by an engine of a crane or does not influence lifting work of the engine or interfere a hydraulic system of the crane, so that the crane works stably. The operation of the air-conditioner does not rely on a power source of a special vehicle, so that the power consumption of the air-conditioner of the special vehicle is greatly lowered, and therefore, the air-conditioner is rational in design and low in carbon and saves energy.

Description

technical field [0001] The present invention relates to air conditioning equipment, more specifically, relates to an air conditioner used in special vehicles and boats. Background technique [0002] A truck crane is a kind of crane installed on an ordinary car chassis or a special car chassis. It belongs to a special vehicle. The driving cab and the lifting control room are set separately. Both the driving cab and the lifting control room need to be equipped with air conditioners. The existing air conditioners in the lifting control room are divided into two types. One is the hydraulic power driven split air conditioner. The disadvantage is that the system pressure fluctuates when the air conditioner is running. , affecting the stability of the crane. If the air conditioner is combined with the oil circuit, it will cause unstable rotation when the load is turned, and the installation and maintenance will be complicated. The other type is DC drive fixed-frequency split air ...
