What are the subsystems and supersystems of electric refrigerators

1. Today, I would like to introduce what the refrigeration system of electric refrigerators includes, roughly including: electric refrigerator compressor, electric refrigerator condenser, electric refrigerator evaporator, electric refrigerator capillaries, etc. They complement each other and are indispensable.

2. Thick frost. Dual system: also known as dual temperature and dual control, there is an added solenoid valve inside, so that the refrigerator and freezer can be separated, independent refrigeration, do not affect each other, and run wherever cold air is needed.Double circulation is more power-saving and quieter than single-cycle, and the temperature control is more accurate. The freezer can also provide higher freezing capacity.

3. Electrical control system, single-door refrigerators, double-door refrigerators, three-door refrigerators, etc. are commonly used in household refrigerators. The electrical control system of the single-door refrigerator is composed of a compressor single-phase motor, a start-up relay, an overload and overheating protector, a temperature controller, an in-box lights and switches, etc.

4. Dual-cycle refrigeration principle: the temperature sensor probe in the refrigerator and the temperature sensor probe in the freezer can control the start-on and shutdown of the refrigerator respectively. Three-circulation refrigeration system: There are three temperature-sensitive probes in the three chambers to control the temperature of the three chambers respectively. The constant temperature of the three doors is 0 degrees for freshness preservation at 0 degrees, and the food preservation and storage time is long.

5. A single-cycle system is an evaporator.+ A fan is to circulate the air in the refrigerator to all corners. The ingredients are easy to smell, and when the refrigerator needs temperature, the freezer is forced to cool. This is generally a low-end model, the price is relatively affordable, and the smell is relatively serious.

Eight laws of technological system evolution, foresee the next Tesla

A complete technical system must Including four parts: power unit;Transmission device; actuator; control device.

The S curve describes the complete life cycle of a technical system. The evolution of a technical system generally goes through four stages, namely infancy, growth, maturity and decline. Infancy.

The merger of Nicola and this SPAC is a catalyst for this industry. Although global demand for electric vehicles is growing slowly, electric vehicle manufacturers and other automotive technology start-ups are competing to obtain the necessary funds to survive and develop their own vehicles.

Logistics All equipment in mobile transportation sends positioning information, equipment identification code and status to the Internet of Things through intelligent labels for unified scheduling and command. Intelligent logistics system: a modern logistics service system that operates in e-commerce on the basis of intelligent transportation system and relevant information technology.

In terms of configuration, the new car will be equipped with Link's latest CoPilot automatic driving assistance system, which has built-in Mobileye SuperVision technology and can support different autonomous driving scenarios such as highways, urban main roads and suburban areas. .

one. What is a system, a subsystem or a supersystem? Give an example 2. Please combine the examples around you (such as washing machine...

1, super system components. It refers to the components in the hypersystem. It is not part of the researched engineering system, but it affects the engineering system. For example, when we study cars, wind, gravity, roads, etc. are all supersystem components.

2. Working principle: The electrical control system of the fully automatic washing machine controls the action of the parts, and realizes the washing and dehydration functions through the clutch conversion of the motor and the reducer clutch; at the same time, the electrical control system also controls the work of the inlet and drainage system, and automatically completes the whole washing process.

3. The evolution of the technical system is more coordinated along the subsystems of the whole system; it develops in a more coordinated direction with the supersystem.

4. The remote control system of the TV adopts infrared pulse and digital coding technology. The automatic control system of the washing machine, one of which adopts timing control technology (the simplest) air conditioning automatic control system, which uses temperature sensors to implement whether the compressor is running. The rice cooker control system, which adopts After the water evaporates.

5. What systems does smart home generally include?Smart home generally includes the following systems: smart home wiring system. Smart home wiring should be said to be a small integrated wiring system. It can be used as a part of a complete intelligent community integrated wiring system, or it can become a completely independent set of integrated wiring systems. Home network system.

6. If a person's life is taken as a system, it can be divided into the following subsystems and levels: physiological system: including various organs and physiological functions of the body, such as respiratory system, digestive system, circulatory system, nervous system, etc. These systems work together to maintain human life activities.

What does supersystem mean

1. Supersystem means that a system is composed of multiple subsystems, and these subsystems can be regarded as independent systems.A supersystem is different from a simple system because it is formed through the interaction of multiple complex systems.

2. In TRIZ theory, hypersystem refers to a larger system network that surpasses the original system under certain specific conditions. Supersystems may be the environment, other systems, or even cosmic systems. It often interacts directly with existing systems, such as matter, energy and information.

3. The problem of car flat tires is a subsystem of the automobile system, and the super system refers to a larger system category containing multiple systems. In the automobile industry, the super system can include vehicle manufacturing, engine manufacturing, fuel manufacturing, battery manufacturing, parts manufacturing, sales channels, maintenance services and other systems.
