Adaptive heat balance control system of ground source heat pump

Abstract

The invention provides an adaptive heat balance control system of a ground source heat pump. The outlet of a water pipe of indoor heat supply air conditioning equipment is connected with a ground source heat pump indoor circulating pump; the outlet of the ground source heat pump indoor circulating pump is connected with the indoor inlet of a ground source heat pump unit; the indoor outlet of the ground source heat pump unit is connected with the indoor heat supply air conditioning equipment; the indoor inlet of the ground source heat pump set is connected with a ground source heat pump outdoor circulating pump; the outdoor outlet of the ground source heat pump unit is connected with an underground pipe and auxiliary heat exchange equipment which are connected in parallel with each other; the outlets of the underground pipe and the auxiliary heat exchange equipment are communicated with the outdoor inlet of the ground source heat pump unit; the control system further comprises an outdoor wet bulb temperature sensor, an underground pipe in and out water temperature sensor, an underground pipe and water pipe flow meter, and a heat balance adaptive controller which works based on a heat balance control underground pipe loop switching valve and a heat exchange equipment loop switching valve. By the adaptive heat balance control system, the running efficiency of the ground source heat pump system is improved, and the heat balance control effect is enhanced.

Description

technical field [0001] The invention relates to a ground source heat pump control system. Background technique [0002] With the development of my country's economy and the continuous improvement of people's living standards, the proportion of energy consumption for heating and air conditioning in the energy structure is also increasing. In building energy saving, the significance of heating and air conditioning energy saving is becoming more and more important. In common heating and air-conditioning systems, cooling in summer and heating in winter operate independently, and the energy structure is mostly conventional energy, which results in low cooling and heating efficiency and serious environmental pollution. A heat pump can absorb heat from a low-temperature environment and release heat to a high-temperature environment. Cooling or heating can be achieved through a simple valve switch. The cooling and heating efficiency of the heat pump is high, and there is basically...
