Directly-heated system

Abstract

The invention discloses a direct heating system, which comprises a condenser, a hot water tank, a controller and a temperature sensor, wherein the condenser is arranged in an air-conditioning system, the hot water tank is connected with the outlet of the condenser, the temperature sensor is used to detest the outlet water temperature of the condenser, the temperature sensor is connected with the signal input interface of the controller, the inlet end of the condenser is equipped with an adjusting device, and the signal output interface of the controller is connected with the adjusting device. The outlet water temperature of the condenser in the air-conditioning system can be precisely controlled without installing a water circulating pump, thereby saving equipments and reducing energy consumption, and can effectively overcome the shortages that the outlet water temperature of the condenser in the air-conditioning system is not stable after heat exchanging.

Description

Technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically relates to a direct heating system that controls the outlet water temperature of the condenser by controlling the water flow in the condenser of the air conditioning system to better meet the needs of production and life. technical background [0002] The heat recovery and thermal energy system in the air conditioning system uses the heat exchange process of the condenser to store heat. The traditional way is to connect the condenser to a water storage tank. The water storage tank returns to the condenser, and the heat is circulated, so that the water in the water storage tank reaches a certain temperature for use in occasions that require hot water. In this process, it is not only necessary to install a water pump to complete the water cycle, but also due to the large water flow in the condenser, the temperature rise in each cycle is small, and it takes mul...

Problems solved by technology

In this process, it is not only necessary to install a water pump to complete the water cycle, but also due to the large water flow in the condenser, the temperature rise in each cycle is small, and it takes multiple heat exchanges to achieve a larger temperature rise. In addition, Since the inlet water temperature of the condenser is not constant, it changes greatly with the influence of seasons and the environment, resulting in uncertain and unstable outlet water temperature, which makes it difficult for users to use, which is neither economical nor accurate.

Therefore, the heat recovery in the traditional air conditioning system has the following defects: a circulating water pump needs to be installed, and the circulating water volume in the condenser is not accurately controlled
