Abstract

The invention relates to a fresh air supply temperature control system based on a variable refrigerant volume (VRV) and fresh air fan hybrid air-conditioning system. The fresh air supply temperature control system comprises a memory module, a fresh air volume calculation module, a VRV coefficient of performance (COP) calculation module, a fresh air fan COP calculation module, a load optimization module and a fresh air supply temperature resetting module. The fresh air supply temperature control system based on the VRV and fresh air fan hybrid air-conditioning system is capable of reasonably adjusting the fresh air supply temperature of a fresh air fan and controlling the indoor temperature while guaranteeing the fresh air supply by carrying out optimal distribution on the load and energy efficiency ratio of a VRV and the fresh air fan, so that the operation stability of the hybrid air-conditioning system is improved, and the energy consumption of the hybrid air-conditioning system is reduced.

Description

technical field [0001] The present invention relates to a technology in the field of building environment and equipment control, in particular to a fresh air supply temperature control system based on a composite air conditioning system of multi-connectors and fresh air fans. Background technique [0002] The variable frequency multi-connected air conditioning system (Variable Refrigerant Volume, VRV, multi-connected for short) has the advantages of simple system, high reliability, and modular design and installation. A number of studies have shown that under the same conditions, the multi-connected system has better energy-saving characteristics than other traditional air-conditioning systems, but its shortcoming of not being able to independently guarantee indoor air quality due to the lack of fresh air introduction has not been properly resolved for a long time. As people's requirements for the living environment are getting higher and higher, indoor air quality (IndoorAi...
