Heat pump equipment

Abstract

The invention is applicable to the technical field of air-conditioner industry and provides heat pump equipment which comprises a low-temperature heat pump system and a high-temperature heat pump system. The low-temperature heat pump system comprises a low-temperature compressor, an intermediate heat exchanger, an economizer, a first liquid storing device, a first expansion valve, a fin heat exchanger and a first gas and liquid separator which sequentially communicate to form a circulation loop. The high-temperature heat pump system comprises a high-temperature compressor, a use side heat exchanger, a second liquid storing device, a second expansion valve, a heat source side heat exchanger and a second gas and liquid separator. The intermediate heat exchanger of the low-temperature heat pump system provides a heat source for the heat source side heat exchanger of the high-temperature heat pump system. According to the equipment, the low-temperature heat pump system provides the heat source for the high-temperature heat pump system, the working medium of the high-temperature heat pump system can absorb enough heat amount to make high-temperature hot water, maximization of the heating efficiency in the ultra-low-temperature environment and the maximum utilization rate of renewable energy sources can be achieved, and the expense of the cost is reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of the air conditioner industry, and in particular relates to a heat pump device. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the energy demand for heating, air conditioning, domestic hot water, etc. is increasing, which is the main part of the energy consumption of general civil buildings. In developed cities, the energy consumed by air conditioning in summer, heating and heating in winter has accounted for 40-50% of the total energy consumption of buildings. In particular, the extensive use of coal-fired boilers and oil-fired boilers for heating in ultra-low temperature environments in northern winter has caused great pollution to the atmospheric environment. Therefore, building pollution control and energy conservation have become a major issue in the development of the national economy. The high-temperature heat pump...
