Air cooling/heating central air-conditioning system

Abstract

An air cooling and heating central air-conditioning system consists of an oil-free air compressor, an ice ball storage heat exchanger, an ice storage bucket, an ice making system, a gas heater, a multifunctional cooling tower, an outdoor unit, an indoor unit, a winter / summer switch, It consists of an adjustable timing reversing valve. The suction pipe of the oil-free air compressor is connected to the top of the multi-functional cooling tower, and the purified air in the suction cooling tower is connected to the winter and summer switch through the compressor exhaust port, and the high temperature in winter The high-pressure air is sent to the gas heater, and then sent to the outdoor unit for heating, and the heated air is sent to the indoor unit to heat up; in summer, the ice hockey storage cold heat exchanger works, and the cold air output by it is sent to the branch air pipe through the main pipe For outdoor units, the air is separated from heat and cold and then sent to the indoor unit for cooling. The present invention overcomes the deficiencies of the prior art and provides an environment-friendly, safe, economical, energy-saving, comfortable and pleasant air cooling and heating central air-conditioning system, which can completely replace the existing central air-conditioning technology.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to an air cooling and heating central air-conditioning system using air as a working medium. Background technique [0002] At present, household air conditioners that use Freon as the working medium are widely used. Although the energy efficiency is relatively high, it can reach more than 2.6. This type of air conditioner has two main disadvantages: [0003] First, Freon is used as the refrigerant, and Freon is the culprit that destroys the ozone layer of the earth's atmosphere and increases the global warming effect. For this reason, countries all over the world have requested to stop the production and use of freon (CFC) within a time limit. [0004] Second, this type of air conditioner cannot provide a large amount of fresh air, and wherein only the window air conditioner can provide a small amount of fresh air, no more than 30%. When this type of air conditioner is used fo...

AI Technical Summary

Problems solved by technology

[0004] Second, this type of air conditioner cannot provide a large amount of fresh air, and only the window air conditioner can provide a small amount of fresh air, no more than 30%

This kind of pipeline can only be hoisted on the top of the corridor, occupying the space of the corridor, making the corridor look low, making people feel depressed, and it is not beautiful, and the cost is relatively high

[0007] Second, this type of air-conditioning system only uses the cooling and heat-carrying characteristics of air, but does not use the cooling and heating characteristics of air, so its energy efficiency ratio is not high, generally between 0.6 and 0.95

Another central air-conditioning system that uses Freon or ammonia as the working fluid can only reach about 1.0 energy efficiency ratio

[0008] Third, although the absorption lithium bromide central air-conditioning system has added a corrosion inhibitor to the system, the corrosion problem of lithium bromide to the equipment has not been completely solved, especially the parts in the pipeline that are in contact with the air are prone to corrosion and affect the equipment. service life

[0009] Fourth, the equipment is relatively large, there are many pipelines, and maintenance is inconvenient
