Embodiment 1

[0033] Embodiment one: if figure 1 As shown, there is provided a kind of radiant cooling and heating wall based on solar energy-ground source heat pump, comprising the thermal insulation layer 2, the heat conduction radiation layer 3, the cement mortar layer 4 and the wall greasy layer 5 arranged on the surface of the building wall 1 in sequence, and the above heat conduction A water media coil 6 is embedded between the radiation layer 3 and the cement mortar layer 4 .

[0034] Among them, the cement mortar 4 and the wall greasy layer 5 form the radiation surface of the radiant cold and hot wall. During use, the water medium coil 6 transfers the heat of the cold water / hot water to the heat conduction radiation layer through contact with the heat conduction radiation layer 3 3, so that the entire heat conduction radiation layer 3 forms a cold and heat radiation surface, that is, the line radiation of the water medium coil 6 is changed into the surface radiation of the heat cond...

Embodiment 2

[0036] Embodiment two: if figure 2 As shown, a household air conditioning system is provided, including a fresh air intake system, a solar collector 11, a hot water tank 12, a chilled water pump 13, a heat exchanger, buried pipes 14, and the above-mentioned radiant cold and hot wall 16;

[0037] The fresh air intake system has a coil heat exchange device 54, and the heat exchanger has a condenser 21 and an evaporator 22;

[0038] The water inlet of the above-mentioned hot water tank 12, the water outlet of the coil heat exchange device 54, the water outlet of the water medium coil 6, and the water inlet of the chilled water pump 13 are respectively connected to the four ports of the first four-way member 7 through pipelines in one-to-one correspondence. A connecting nozzle, the water outlet of the above-mentioned chilled water pump 13 is respectively connected to the water inlet of the above-mentioned condenser 21 and the evaporator 22 through pipelines;

[0039] The water o...

Abstract

The invention relates to the technical field of heat exchange, in particular to a cold and heat radiation wall based on a solar energy-ground source heat pump and a household air conditioning system. The cold and heat radiation wall based on the solar energy-ground source heat pump comprises a heat preservation layer, a heat-conducting radiation layer, a cement mortar layer and a wall surface putty layer which are sequentially arranged on the surface of a building wall body, wherein a water medium coil is embedded between the heat-conducting radiation layer and the cement mortar layer. The household air conditioning system comprises a fresh air inlet system, a solar heat connector, a hot water tank, a frozen water pump, a heat exchanger, a buried pipe and the cold and heat radiation wall. The cold and heat radiation wall has the advantages of being simple in structure, saving energy, being good in comfort, facilitating achievement of 'household metering and household adjustment' and transferring peak value power consumption on the cold and heat radiation aspect, and the like. The whole system is reasonable in design, convenient to use and lower in energy consumption, and the using cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a solar-ground source heat pump-based radiation cooling and heating wall and a household air-conditioning system. Background technique [0002] At present, the applications of heating and cooling air conditioners, solar collectors, and ground source heat pumps on the market are mostly independent, especially in residential buildings. Most of the indoor heat exchangers of heating and cooling air conditioners in residential buildings are fan coil units, floor coil radiation, roof coil radiation and radiators. Bacteria are easy to breed on the condensate pan of the fan coil unit, which will pollute the indoor air; Tube radiation and roof coil radiation, the former can only be used for radiant heating, the latter can only be used for radiant cooling, that is, cooling and heating cannot be performed at the same time; the radiator is similar to the previous two, it can only provi...
