Problems solved by technology

However, although the traditional full heat recovery air-cooled hot and cold water units have multiple operating modes, such as air-conditioning cold water production, air-conditioning hot water production, domestic hot water production and heat recovery mode, most of these modes operate independently
When mode conversion is required, it often needs to be realized manually, which not only greatly reduces the convenience, but also increases the maintenance cost of customers, reduces the practicability of the unit, and affects the promotion and use

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 Shown is a full heat recovery air-cooled chiller or hot water unit.

[0020] When cooling water in the air conditioner, the refrigerant circulates along the following circuit: the air outlet of the compressor 18—the 1A port of the first four-way reversing valve—the 1B port of the first four-way reversing valve—the port of the second four-way reversing valve 2 A' port - the second four-way reversing valve 2B' port - air heat exchanger 3 - the second one-way valve 11 - the third filter 12 - the second throttling component 15 - the fourth filter Device 14 - water heat exchanger 16 - second four-way reversing valve 2D' port - second four-way reversing valve 2C' port - gas-liquid separator 17 - compressor 18 air return port.

[0021] When making hot water for air conditioning, the second four-way reversing valve 2 is switched on or ...

Abstract

The invention relates to a control method of a total heat recovery air-cooled cold water or hot water unit, including a refrigeration cycle device composed of a finned copper tube heat exchanger, an air-conditioning water side heat exchanger and a domestic hot water heat exchanger, and an installation The temperature sensors in the water inlet of the air conditioner, the water tank of the unit and the environment of the unit can realize the automatic switching of the unit between different operation modes by monitoring the temperature of the water inlet of the air conditioner and the temperature of the water tank, effectively improving the operating efficiency of the unit and reducing maintenance costs . At the same time, it can also reduce the frequent start and stop of the unit and prolong the service life.

Description

technical field [0001] The invention relates to a control method of an air conditioning system, in particular to a control method of a total heat recovery air-cooled cold water or hot water unit. Background technique [0002] At present, air-cooled hot and cold water units with full heat recovery in the commercial field have been widely used. However, although the traditional full heat recovery air-cooled hot and cold water units have multiple operating modes, such as air-conditioning cold water production, air-conditioning hot water production, domestic hot water production and heat recovery mode, most of these modes operate independently. When mode conversion is required, it often needs to be realized manually, which not only greatly reduces the convenience, but also increases the maintenance cost of the customer, reduces the practicability of the unit, and affects the promotion and use. Contents of the invention [0003] The purpose of the present invention is to addre...
