Hot water air conditioning device of sleeve and fin type heat exchanger

Abstract

The invention discloses a hot water air conditioning device of a sleeve and fin type heat exchanger. The air conditioning device comprises a first compressor, an evaporator, a first throttling device, the sleeve and fin type heat exchanger, a second compressor, a water heater, a second throttling device, a first blower, a second blower, a second stop valve, a third stop valve and a fourth stop valve, wherein a refrigerant air outlet end of the first compressor is connected with a first port on a refrigerant side of the sleeve and fin type heat exchanger; a third port on the refrigerant side of the sleeve and fin type heat exchanger is connected with an inlet end of the first throttling device; an outlet end of the first throttling device is connected with an inlet of the evaporator; an outlet of the evaporator is connected with an inlet end of the first compressor; an inlet of the first blower is connected with an outlet in an air side of the evaporator; and the second blower is connected with an outlet in an air side of the sleeve and fin type heat exchanger. The hot water air conditioning device can replace conventional water heaters such as an electrical heater, a boiler heater and the like, an efficient, safe and pollution-free water heating process is realized, particularly when the hot water air conditioning device is used in a building in a tropical zone, air conditioning cooling and hot water preparing can be realized at the same time, heat transferred from an air conditioning area is effectively used, and the energy benefit of a whole system is high.

Description

【Technical field】 [0001] The invention relates to a hot water air conditioner with a casing fin heat exchanger. 【Background technique】 [0002] The water heating equipment currently used in tropical areas mainly includes the following types: [0003] 1. Boiler heating produces hot water. The main process of this method includes the combustion process of fuel, the heat transfer process of flue gas to water and the heating process of water. The hot water of the required temperature is produced through the above process, but there are the following problems: 1. The fuel is usually an unclean energy source, and the combustion of the fuel is easy to form smoke to pollute the environment, and it usually needs to be processed at an expensive price; 2. The process Medium energy is converted from high-grade energy to low-grade energy, and there is irreversible energy loss; 3. With the rise of energy prices, the operating cost of equipment continues to increase, and its economy is p...

Problems solved by technology

The hot water of the required temperature is produced through the above process, but there are the following problems: 1. The fuel is usually an unclean energy source, and the combustion of the fuel is easy to form smoke to pollute the environment, and it usually needs to be processed at an expensive price; 2. The process Medium energy is converted from high-grade energy to low-grade energy, and there is irreversible energy loss; 3. With the rise of energy prices, the operating cost of equipment continues to increase, and its economy is poor

In the above equipment, the electric heating component is the core component, and there is no pollution during the heating process, but there are the following disadvantages: 1. The conversion of electric energy into heat energy consumes a lot, and with the rise of energy prices, the operating cost increases; 2. The acquisition of electric energy is huge. Consumes primary energy, and has disadvantages such as high pollution and low benefit

Compared with the above two methods, this method has obvious energy-saving benefits, but it has the following disadvantages: while making hot water, it does not make full use of the cooling capacity generated by the system

But there is a disadvantage of not using heat

[0007] When a building needs hot water and air conditioning at the same time, it is usually necessary to set up a set of air conditioning equipment and a set of hot water equipment, which increases the initial investment and operating costs of the equipment
