Air-source central air-conditioning hot water triple-generation heat pump unit

Abstract

An air-source central air-conditioning hot water triple-generation heat pump unit comprises a compressor, a solar hot water pump, a hot water return pump, a hot water tank, a hot water solenoid valve, an air-conditioning solenoid valve, a four-way valve, a check valve group I, a case, a fan, a check valve group II, an air-source heat exchanger, an air-conditioning heat exchanger, a filter, an air-conditioning water pump, an energy storage tank, a thermal expansion valve I, a balance throttle pipe, a balance solenoid valve, a thermal expansion valve II, a liquid storage tank, an economizer, a liquid-vapor separator and a connecting line. By action of the balance throttle pipe, the check valve groups, the hot water tank and the air-source heat exchanger, the defect that traditional ground source heat pump units are not suitable for being promoted in regions with high building densities and projects with large air conditioning loads is overcome, the source efficiency ratio is improved effectively, health hot water at the temperature of 65DEG C is supplied, the problem of insufficient heat temperatures of hot water caused by inadequate refrigeration in transition seasons is solved, the hot water is output directly through tap water pressure, the dual hot water function of air source and solar energy is achieved, and heating is achieved without electricity at the temperature of minus 20DEG C in winter.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning heating and cooling, in particular to an air-source central air-conditioning hot water triple heat supply heat pump unit. Background technique [0002] Traditional central air-conditioning hot water triple heat pump units mainly include the following three types: [0003] 1. Ground source central air-conditioning hot water triple heat supply heat pump unit [0004] Utilizing the nature of shallow underground soil, or river water, or the large cold and heat capacity of underground water sources, the heat exchanger is buried in shallow underground soil, or rivers, or underground water sources, or directly pumped from rivers or underground water sources, and made through water. The medium exchanges heat and cold with the shallow underground soil, rivers and underground water sources, and the water is exchanged for cold and heat through the ground source heat pump unit, that is, by i...

Problems solved by technology

[0012] The technical problem solved by the present invention is to provide an air-source central air-conditioning hot water triple heat pump unit, which overcomes the disadvantage that the traditional ground-source heat pump unit is not suitable for promotion in areas with high building density and projects with large air-conditioning loads, and at the same time It solves the problem of low source-efficiency ratio caused by frequent defrosting and electric auxiliary heating of traditional air-source heat pump units for heating air-source heat exchangers in winter; and provides 65°C sanitary hot water, which effectively solves the problem of cooling and cooling in spring and autumn transitional seasons. When the hot water is combined, the heating temperature of the hot water is not enough due to insufficient cooling. It has the functions of hot water directly outputting through tap water pressure, air source and solar energy, so as to solve the above-mentioned shortcomings in the background technology.
