Dual temperature unit heat exchange station

Abstract

The invention relates to a double-temperature-state unit heat exchange station, which comprises a machine frame, a first water mixing tank, a second water mixing tank and a plate type heat exchanger, wherein the plate type heat exchanger is provided with a primary water inlet, a primary water outlet, a secondary water inlet and a secondary water outlet, the first water mixing tank is provided with a cold and heat source water inlet, an air exchange machine water outlet, a heat exchanger water outlet and a first bypass opening, the second water mixing tank is provided with an air exchange machine water return opening, a heat exchanger water return opening, a cold and heat source water outlet and a second bypass opening, the heat exchanger water outlet is communicated with the primary water inlet of the plate type heat exchanger, the primary water outlet of the plate type heat exchanger is communicated with the heat exchanger water return opening through a pipeline, and the first bypass opening and the second bypass opening are mutually connected through a pipeline provided with a pressure difference bypass valve. The double-temperature-state unit heat exchange station has the advantages that the machine room part of a central air-conditioning system is fully integrated, two kinds of temperature required by refrigeration dehumidification fresh air and high-temperature radiation can be simultaneously met, the installation work period of the central air-conditioning system is shortened, and the problem of excessive dependence on blue-collar workers of construction teams is effectively solved.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning heat exchange control, in particular to a dual-temperature state unit heat exchange station. Background technique [0002] At present, for the traditional central air-conditioning system, the machine room part is usually non-standardized and tailored according to different sites, resulting in high requirements for installation workers on site; now, there is a growing shortage of blue-collar technical talents, and the speed of market engineering construction is accelerating. , the lack of technical personnel is one of the main reasons leading to project failure. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a dual-temperature unit heat exchange station that is convenient for installation and construction and has a good degree of standardization, which is specifically realized by the following technical solutions...
