The invention provides a condenser pipe box, a condenser, a control method, a control device and an air conditioning unit. The condenser pipe box comprises a box body, and a first water pipe and a second water pipe which are arranged on the box body, wherein a first port is formed in the side wall of the first water pipe, and a second port and a third port are formed in the side wall of the second water pipe. According to the condenser pipe box, a water inlet temperature and the change rate of the water inlet temperature are obtained, the relationship between the water inlet temperature and a heating water inlet set temperature is determined, and at least two compressor systems are adjusted according to the relationship between the water inlet temperature and the preset heating water inlet set temperature and the relationship between the water inlet temperature change rate and a preset water inlet temperate change rate. Therefore, measured water inlet and outlet temperature and flow are real situations of water inlet and outlet temperature and flow for the condenser, and the control precision of a shell and tube type air conditioning unit during heating load control is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, relates to a condenser tube box, a condenser, a control method, a device and an air conditioning unit. Background technique [0002] The shell-and-tube air conditioning unit uses a shell-and-tube condenser for heat exchange. During the operation of the shell-and-tube air-conditioning unit, load control and / or flow control can be performed by monitoring the inlet and outlet water temperatures and water flow of the shell-and-tube condenser. [0003] However, the inventor found in the process of realizing the present invention that due to the structural constraints of the condenser tube box, and according to the actual environment of the engineering installation of the shell-and-tube air-conditioning unit, the temperature of the inlet and outlet water of the shell-and-tube condenser and the water flow detection point The location of the shell-and-tube condenser will ...
