Air conditioning

Air conditioning (often referred to as A/C or AC) is the process of altering the properties of air (primarily temperature and humidity) to more comfortable conditions, typically with the aim of distributing the conditioned air to an occupied space such as a building or a vehicle to improve thermal comfort and indoor air quality. In common use, an air conditioner is a device that lowers the air temperature. The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants.

In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, cooling, (de-)humidification, cleaning, ventilation, or air movement). However, in construction, such a complete system of heating, ventilation, and air conditioning is referred to as heating, ventilation, and air conditioning (HVAC -as opposed to AC).

History

The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window. This process also made the air more humid, which can be beneficial in a dry desert climate. In Ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season.

Toyota A engine

The A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads.

The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes the first mass-production DOHC, four-valve-per-cylinder engine, the 4A-GE, and a later version of the same motor was one of the first production five-valve-per-cylinder engines.

Toyota joint venture partner Tianjin FAW Xiali still produces the 1.3 L 8A and recently resumed production of the 5A.

1A

The 1.5 L 1A was produced between 1978 and 1980. All variants were belt-driven 8-valve counter-flow SOHC engine with a single, twin-barrel downdraft carburetor.
