Cold and hot water heat pump and heat source tower heat pump low-cost test bed operating in wide working condition

Abstract

The invention relates to a cold and hot water heat pump and a heat source tower heat pump low-cost test bed operating in a wide working condition. The low-cost test bed comprises a cold and heat supply system, a unit test system and an intermediate pipeline valve system. The cold and heat supply system comprises a working condition machine, a hot water tank, a cold water tank and a cooling tower.The unit test system comprises an air conditioning cabinet, a cold-side heat exchanger, a hot-side heat exchanger, an expansion water tank, an electric valve, a flowmeter and a water pump. The middlepipeline valve system comprises a butterfly valve and a water pump. The experiment table can realize performance test and scientific research of a heat source tower heat pump all-in-one machine and acold and hot water heat pump unit product under different high and low temperature working conditions and cold and heat conditions. The experiment table effectively utilizes the cold source of the tested machine, reduces the energy consumption of the working condition machine, and achieves the energy-saving effect. The experiment table is optimally provided with an optimal working condition machine, and the effects of multiple working conditions and low cost are achieved. The experiment table fills the blank of the prior art in the technical field.

Description

technical field [0001] The invention relates to a dual-purpose detection device for a heat source tower and a cold and hot water heat pump unit, more specifically, it relates to an energy-saving test bench for a cold and hot water heat pump and a heat source tower heat pump unit applicable to both high and low temperature working conditions at low cost. Background technique [0002] The existing central air-conditioning cold and heat source systems have their own advantages and disadvantages: water ground source heat pumps take into account both cooling and heating, and have high efficiency, but are limited by geographical conditions and require high initial investment. The phenomenon of heat imbalance affects heat exchange; the chiller plus boiler has high cooling efficiency and compact structure, but the boiler heating energy utilization rate is low; the air source heat pump has a small structure and can provide both cooling and heating, but the cooling efficiency in summer...
