Air temperature adjusting system for heat exchange type vehicles and vessels

Abstract

The invention relates to an air temperature adjusting system for heat exchange type vehicles and vessels, which comprises an evaporator using alcohol refrigerant, condenser, an ejecting and sucking device, a pump, a heater and a liquid storage tank. The ejecting and sucking device is capable of sucking refrigerant in the evaporator and outputting the refrigerant to the condenser, and the heater is capable of absorbing heat of engine tail gas by means of heat exchanging to vaporize the refrigerant. The heater is connected between the ejecting and sucking device and the pump through a pipe, and the evaporator comprises both of or one of an air-conditioning evaporator and a cooling evaporator. The evaporator is disposed on an engine air inlet pipe or arranged in an engine air inlet filter and used for cooling air flowing into an engine, dropping of air inlet temperature can improve air sucking efficiency of the engine, the engine can be in or close to the optimum operating state, engine power is improved, fuel consumption is reduced, and waste gas emission is reduced.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a heat exchange type air temperature regulating system for vehicles and ships that can cool or heat the air sucked by the internal combustion engine. Background technique [0002] In the hot summer, the air density decreases due to the increase of air temperature. In the engine room where the car and boat engine is placed, the air is not circulated so that the temperature is as high as hundreds of degrees. When the engine is working, the air is relatively high in temperature. It greatly reduces the intake efficiency of the engine, which in turn affects the best working state of the engine, reduces engine power, increases fuel consumption, and increases exhaust emissions; in cold winter, too low intake air temperature also causes Decreased engine performance. From the perspective of the ride comfort of the drivers and passengers, the high temperature air in the hot seas...
