At present, the ground source heat pump air-conditioning unit with full heat recovery used in China can prepare hot water, but due to the real-time change of heat load, it can only guarantee the water supply of domestic hot water, but cannot guarantee the water supply temperature, so it cannot meet certain requirements. Where the temperature of domestic hot water is required
At present, places in China that have temperature requirements for domestic hot water usually use traditional heating methods such as boilers, and secondly, abandon the use of full heat recovery, resulting in a lot of energy waste

The invention relates to a constant-temperature control system for domestic hot water of a total-heat recovery ground source heat pump air conditioner. The constant-temperature control system comprises the total-heat recovery ground source heat pump air conditioner, wherein the total-heat recovery ground source heat pump air conditioner comprises a domestic hot water tank, a plate heat exchanger, a heat pump unit with heat recovery, a heat pump unit without heat recovery, an air conditioning terminal and a ground source side system; the plate heat exchanger comprises two inlets and two outlets; the heat pump unit with heat recovery comprises three inlets and three outlets; the heat pump unit without heat recovery comprises two inlets and two outlets; and the constant-temperature control system comprises a control box, a temperature transducer, a plate exchange side circulating pump, a heat recovery circulating pump, first to fourth ground source side circulating pumps and an electric switch valve. The constant-temperature control system can guarantee the domestic hot water to reach a needed temperature requirement when guaranteeing stable operation of an air conditioning system.
Description
technical field [0001] The invention relates to a constant temperature control system for ground source heat pump air-conditioning domestic hot water with full heat recovery, especially suitable for places such as hotels, hotels, hospitals, etc. that have a large demand for air conditioning and hot water, and at the same time have certain requirements for the temperature of domestic hot water. Background technique [0002] The consumption of domestic hot water in some specific occasions is huge, and because of the flow of people at any time and other reasons, the consumption of hot water also changes in time. At the same time, some specific places, such as hotels, hotels, hospitals, etc., have certain requirements for the temperature of domestic hot water. This causes the heat load of domestic hot water to change in real time. At present, the ground source heat pump air-conditioning unit with full heat recovery used in China can prepare hot water, but due to the real-time c...
