Intelligent control system for direct evaporation type multi-heat-exchange-system ice cold storage air conditioner

Abstract

The invention discloses an intelligent control system for a direct evaporation type multi-heat-exchange-system ice cold storage air conditioner, which belongs to the field of ice cold storage air conditioners. The intelligent control system comprises an air conditioner main unit and ice tanks, wherein one end of the condenser (6) of the air conditioner main unit is connected with the first end of an evaporator (3) through a pipe, a first electromagnetic valve (5) and a first thermal expansion valve (4), and the other end of the condenser (6) is connected with the first ends of a plurality of groups of parallelly connected ice tanks by pipes; the second ends of the plurality of groups of parallelly connected ice tanks are connected with the other end of a vapor and liquid separator (8) by pipes; the third ends of the plurality of groups of ice tanks are connected in parallel and connected to the pipe of a first reversing electromagnetic valve (1) by pipes and a third reversing electromagnetic valve (22); the fourth ends of the plurality of groups of ice tanks are connected in parallel and are connected to a pipe of a second reversing electromagnetic valve (2) by pipes and a fourth reversing electromagnetic valve (21); and the first reversing electromagnetic valve (1) and the second reversing electromagnetic valve (2) are connected with an air conditioner tail end unit (16). The intelligent control system requires small investment and achieves a good energy-saving effect.

Description

technical field [0001] The invention relates to an intelligent control system for an ice-storage air conditioner of a direct evaporative multi-heat exchange system, belonging to the field of ice-storage air conditioners. It can be widely used in office buildings, shopping malls, supermarkets, theaters and other places that use refrigerant water systems, especially where the power consumption of the existing air conditioning system exceeds the applied power load and urgently needs additional air conditioning cooling capacity. Background technique [0002] Cold storage technology is to use the time when the power grid is at a low price at night, the system runs at full capacity to make ice and store cold during the peak power consumption during the day, so as to save the operating cost of the air conditioner, reduce the installed capacity and power consumption of the refrigeration host, so as to realize the transfer of peak power load and balance the pipe network purpose of po...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: to overcome the contradiction between the uneven day and night load of the conventional chiller air-conditioning system and the difference between the peak and valley electricity prices of the power pipe network, and to simply add a whole set of ice storage system to save energy and reduce emissions, but the initial investment If the contradiction is too high, provide a direct evaporative multi-heat exchange system ice storage air-conditioning intelligent control system with small investment and good energy-saving and emission-reduction effects
