Thermodynamic Simulation of CCP in Air-Cooled Heat Pump Unit with HFCs and CO&lt;sub&gt;2&lt;/sub&gt; Trans-Critical

This paper describes the research and implementation of ground source heat pump unit remote real-time monitoring system, researches in remote real-time monitoring system's overall design, hardware design, software design and implementation of OPC communication. The host computer takes advantage of the human-computer interaction interface of configuration software to achieve the remote real-time monitoring for ground source heat pump unit's running state; the lower computer uses data collector to intensively collect the data which is measured by field measuring instruments, and to achieve remote data transmission based on Ethernet, and then to carry out the communication between the host computer and the lower computer via OPC technology. The results show that the system achieves remote real-time monitoring of ground source heat pump unit, and is stable, easy to operate and provides a reliable basis for the actual energy saving effect's evaluation of ground source heat pump system.

This paper analyses the energy consumption of water source heat pump, shows that the performance coefficient of water source heat pump unit is directly related to the temperature of water resources, and discusses the feasibility of central heating by recovering condensing heat of power plant using water source heat pump unit. It analyzes the energy saving benefit of water source heat pump unit is significant compared with traditional heating. Using the technology recovers waste heat of power plant, which can not only decrease the energy waste on the direct discharge of waste heat and water, but at the same time, it is a new air conditioning system without environmental pollution.

Monitoring Software

Performance test-bed of heat pump unit in central air-conditioner needs the intelligent and multifunctional software. So the monitoring software is designed with a good human-machine interactive interface, based on Visual C# development platform. The software can dynamically configure channels and measurement points to improve the defects of fixed channels for all measuring points in the traditional monitoring systems, which enhanced the flexibility and reliability of system. In order to increase the data accuracy, the improved digital filter algorithm was adopted. In addition, multi-threading mechanism was used to achieve serial communication and data processing, which meets the requirements of monitoring program for multi-tasking and real-time. The results show that monitoring software is powerful, easy to operate, reliable, high fault-tolerant and good user-friendly. It is suitable for using in other monitoring systems.
