Technology is developing and the times are improving. As a new business opportunity, the cold chain transportation industry has attracted the attention of thousands of companies and scientific and technological personnel. Solar refrigerated trucks have been independently developed by China, filling the gap in the production of domestic solar refrigerated trucks . Traditional fuel-powered refrigeration is the frequent start of generator cooling mode. It has high requirements for generators and large losses. It also emits gas that pollutes the environment. Solar cooling can greatly reduce energy consumption, noise, and environmental pollution. It is a new type of environmental protection. Refrigerated vehicle. The new solar refrigerated truck has the following advantages: 1. Low energy consumption and low emission. It uses solar energy to generate electricity. Through a reversed-electricity conversion system, it greatly saves energy and reduces exhaust emissions. 2. The appearance is exquisite. Just add a photovoltaic panel at the top of the car. 3, easy to use. The solar car is equipped with an automatic switching system for energy supply, which can use conventional energy sources for energy supply in bad weather conditions. 4, 100 kilometers and 10% -12% oil. 5, 100 kilometers can reduce the carbon dioxide emission of about 1.5Kg. 6, 100 kilometers can reduce carbon emissions around 0.5Kg. 7, using high efficiency DC brushless motor, running more smoothly. 8, reduce the number of engine starts and delay the life of the engine. 9, fast cooling and cooling, improve work efficiency, reduce engine energy consumption. 10. When cargo is loaded or unloaded, cargo and personnel can be protected from the pollution of exhaust emissions. 11. When parking, make sure that the contents of the box can maintain the initial fresh state. 12, in line with national food safety regulations, to achieve green food distribution.

The solar cold storage system is a new type of system that uses solar energy resources to provide energy for the on-board cold storage system. This system uses the inexhaustible natural resources of solar energy to provide electric energy to the vehicle as much as possible. The refrigeration system is cycled and at the same time it guarantees the freshness of the cold storage cargo in the event of an engine shutdown. Solar refrigerated trucks will become a new trend in the future.

A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y Ramírez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
