Direct-fired type constant-temperature and constant-humidity air conditioning system for ship and working method

Abstract

The invention discloses a direct-fired type constant-temperature and constant-humidity air conditioning system for a ship and a working method. The direct-fired type constant-temperature and constant-humidity air conditioning system for the ship comprises a heat pump subsystem, a solution dehumidifying subsystem, a waste heat humidifying subsystem, an air delivery duct, an air filter, a temperature sensor and a humidity sensor. A Stirling engine taking natural gas as fuel drives a compressor directly to complete steam compression work, the transmission loss of the work quantity is avoided, andthe energy utilization rate is increased; through the low-temperature seawater and flue gas waste heat utilization technology, the problem of poor refrigerating and heating performance of the air conditioning system for the ship is solved effectively, and the energy efficiency coefficient of the air conditioning system for the ship is increased; and through the waste-heat-driven spraying humidifying and solution dehumidifying technology, the humidity value is adjusted comfortably, and the air quality is improved. The novel constant-temperature and constant-humidity air conditioning system forthe ship is constructed in a mode of independent control over the temperature and the humidity, the system plays a main role in refrigerating / heating and an auxiliary role in humidifying / dehumidifying, and after an existing energy-saving technology and air treatment technology are integrated, the effect of constant-temperature and constant-humidity comfortable adjusting of air in a ship compartment is achieved.

Description

technical field [0001] The invention relates to a direct-fired marine constant-temperature and constant-humidity air-conditioning system and a working method, in particular to a direct-fired marine constant-temperature and constant-humidity air-conditioning system, which belongs to the technical field of energy and air-conditioning engineering. Background technique [0002] "Temperature" and "humidity" are respectively one of the "four degrees" of air conditioning, and are of great significance in maintaining human comfort. Generally speaking, the suitable ambient temperature value is around 25°C, and the suitable ambient relative humidity value is between 40% and 60%. The value also increasingly reflects its importance. Realizing high-quality air conditioning and improving existing air-conditioning devices have become a topic of concern to the refrigeration and air-conditioning industry. [0003] In the process of improving the air-conditioning device, the constant tempera...
