Description
Technical Field

Background
At present, a combined air conditioner and a return exhaust fan are arranged in a public area of a subway station, a cabinet air conditioner and a return exhaust fan combined form are arranged in a management room, a primary return air conditioning system is adopted for refrigerating in summer, ventilation is carried out in a transitional season, and outdoor fresh air is introduced in winter to meet the fresh air requirements of the public area and the management room. However, the outdoor fresh air is cold in winter, the fresh air is directly sent to a public area, no heating measures are taken in the public area, and the temperature of the public area is usually lower than the 12 ℃ required by the specification, so that the comfort level of passengers is poor. The management house is generally provided with an electric heater or a multi-split air conditioning system for heating and warming in winter. Because of radiation heating, the electric heater has a relatively short heat transfer distance, a relatively poor overall heating effect of a room, poor comfort and high energy consumption. The indoor units of the multi-split air conditioning system occupy larger space in a suspended ceiling, the comprehensive pipeline arrangement pressure is larger, the system is complex, the power consumption in winter is large, the heating efficiency is lower, and the heating efficiency is lower in cold areas.
The heat productivity of the electric equipment in the weak electric equipment room and the power supply equipment room is larger, the standard station can reach 200 kw-250 kw, and in order to ensure that the equipment room is not over-temperature, an exhaust fan is still required to be started in winter to remove the redundant heat outdoors, so that the electric equipment room not only consumes electricity, but also causes waste of waste heat.
The heat pipe can be divided into an evaporation section, a heat insulation section and a condensation section, when the heat source supplies heat to the heat pipe in the evaporation section, the working medium absorbs heat and is vaporized from the heat source to become steam, the steam flows to the other end along the middle channel at a high speed under the action of pressure difference, and the steam is condensed into liquid after releasing latent heat to the cold source in the condensation section; when the working medium evaporates in the evaporation section, the gas-liquid interface is concave to form a plurality of meniscus liquid surfaces to generate capillary pressure, the liquid working medium returns to the evaporation section under the action of the reflux power of the capillary pressure of the tube core, gravity and the like to continue to absorb heat and evaporate, and the working medium is circularly reciprocated in this way, so that the heat is continuously transferred from the hot end to the cold end by the evaporation and condensation of the working medium.
Compared with other heat exchangers, the heat pipe heat exchanger has unique advantages, is extremely convenient and fast in the use process, has better conduction effect, and is a low-temperature heat pipe in the process of recovering energy sources in the operation process of the ventilation air conditioner. The low-temperature heat pipe heat exchanger uses the temperature difference between exhaust air and air supply, adopts a low-temperature heat pipe as a heat exchange element, and improves the air supply temperature through heat exchange, thereby achieving the purpose of energy recovery. The exhaust fan discharges the indoor air containing heat to the outside through the evaporating section of the heat pipe, and the blower sends the outdoor low-temperature air to the conditioned room through the condensing section of the heat pipe. The heat of the indoor exhaust air is recovered, so that fresh air is heated and sent into a conditioned room, and the purposes of energy conservation and heat exchange are achieved. The heat pipe heat exchanger is widely used in the fields of boilers, ceramics, chemical industry, traffic and the like at present, and has not been applied in subway stations.
