Chilled water way system, adjusting method of system, water chilling unit and air conditioner

Abstract

The invention provides a chilled water way system. The system comprises a chilled water way and a water pump; a heat exchanger is connected in the chilled water way; the water pump is connected in the chilled water way and is used for driving chilled water to circulate in the chilled water way; the chilled water way comprises at least two chilled water inlet ways which are connected with a chilled water inlet of the heat exchanger in a converged manner; and the water pump is connected with the at least two chilled water inlet ways so as to control opening and closing of the chilled water inlet ways. Thus, according to the chilled water inlet and outlet temperature difference and the chilled water outlet temperature, opening and closing of the chilled water inlet ways are controlled, the flow of the chilled water is adjusted, the chilled water inlet and outlet temperature difference is matched with the indoor load, the degree of heat exchange between the chilled water and a refrigerant in the heat exchanger is guaranteed, and the refrigeration comfort is guaranteed. Besides, the chilled water outlet temperature is within the reasonable range, and the service life of a refrigeration component is guaranteed. The invention further provides an adjusting method of the chilled water way system, a water chilling unit and an air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a refrigerant water system and an adjustment method thereof, a water chiller and an air conditioner. Background technique [0002] The air conditioning system of the combination of chillers and air conditioning terminal products is a system mode that is widely used in building air conditioning. With the development of air-conditioning technology, energy saving has become an important indicator for evaluating the performance of air-conditioning. For chillers, the control of water pumps plays an important role in the energy-saving of air-conditioning. [0003] At present, energy-saving control is usually achieved by controlling the frequency conversion of the water pump, but the control principle is complicated and it is difficult to ensure the comfort of the air conditioner. In addition, chillers often use plate heat exchangers with high heat transfer coefficients, but the thickne...
