[0003] At present, the arrangement of the flasher in the refrigeration unit is installed on or around the top of the condenser and the evaporator, which not only increases the volume of the refrigeration unit, but also needs to be adjusted in order to reduce the waste of cooling capacity of the unit. Insulation measures for the flasher (usually wrapping the flasher with multiple layers of insulation cotton), which also increases the cost of the unit
In addition, the amount of air supplied to the compressor by the flasher in this arrangement is completely determined by the performance of the throttling element between the flasher and the condenser. Therefore, there will often be phenomenon of air supply with liquid or insufficient air supply, which seriously affects Reliability and performance of refrigeration units

Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] figure 1 Shown is the structural representation of the shell-and-tube condenser in one of the embodiments of the present invention, as can be seen from this figure, the shell-and-tube condenser 1 in the present embodiment is a horizontal shell-and-tube condenser 1 (also can It is a vertical shell-and-tube condenser), which mainly consists of a shell 11, a heat exchange tube bundle 12 arranged at the inner bottom of the shell 11, and a flasher 13 arranged at the upper part of the shell 11, and the top and bottom of the shell 11 are respectively A condenser inlet 111 and a condenser liquid outlet 112 are provided, and the condenser inlet 111 is used to communicate with the exhaust port of the compressor.
[0022] The flasher 13 is arranged horizontally in the shell, and can be fixed with the condenser 1 by welding. The flasher 13 has a flasher liquid...

The invention discloses a shell-and-tube condenser. The condenser comprises a shell and a heat exchange tube bundle and a flash-tank which are arranged in the shell. A condenser air inlet and a condenser liquid outlet are arranged in the top and the bottom of the shell respectively, the flash-tank is provided with a flash-tank liquid inlet, a flash-tank liquid outlet and a flash-tank air outlet, and the flash-tank liquid inlet is communicated with the condenser liquid outlet. According to the shell-and-tube condenser, the flash-tank is arranged in the condenser, the air supplementing amount of a compressor is increased through the interior and exterior temperature difference of the flash-tank, the compressor performance is improved, and cooling capacity waste of a refrigerating unit is reduced. Besides, the flash-tank is arranged in the condenser, so that the volume of the refrigerating unit is effectively reduced, and the refrigerating unit room area is further reduced. The invention further discloses an air conditioning system with the shell-and-tube condenser.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a shell-and-tube condenser and an air-conditioning system provided with the shell-and-tube condenser. Background technique [0002] The flasher (also known as the economizer) is set up to reduce the power consumption of the unit. It mainly introduces the throttling flash saturated refrigerant gas from the condenser to the second stage of compression. The high temperature and high pressure gas is mixed, thereby reducing the gas temperature at the inlet of the secondary compression, and achieving the purpose of reducing the power consumption of the unit. [0003] At present, the arrangement of the flasher in the refrigeration unit is installed on or around the top of the condenser and the evaporator, which not only increases the volume of the refrigeration unit, but also needs to be adjusted in order to reduce the waste of cooling capacity of the unit. Insulation measures are taken...
