Embodiment Construction

[0021] The cooling mode (air conditioning in summer and hot water heating at the same time), the heating mode (hot water heating at the same time) and the hot water heating mode of the present invention will be described below with reference to FIG. 1 to FIG. 3 . In the embodiment shown in Fig. 1 to Fig. 3, the underground heat exchanger 10 adopts three loops, and only one loop located downstream of the first one-way valve 9 is used during cooling operation.

[0022] (1) Cooling mode

[0023] Combined with Figure 1 to illustrate. Compressor 1 starts. The A end of the four-way valve 2 is connected to the D end, and the B end is connected to the C end. The first solenoid valve 5A is opened, and the second solenoid valve 5B and the third solenoid valve 5C are closed. That is, when the underground heat exchanger 10 has 2 to 3 loops, only one loop is used in the cooling operation, so the solenoid valve 5C is closed.

[0024] The high-temperature and high-pressure gas refrigeran...

Abstract

There is a straight swell ground source heat pumping conditioner water heater. It has the multifunction such as heat collecting, air conditioner and heat supplying, which is suitable to the living house and small business architecture, and which belongs to the centre conditioner hot water equipment. The compressor of this invention air inlet is connected with the B part of quad valve by the gas and liquid separator, and the outlet of the compressor is connected with the A part of the quad valve by the heat changer of the water box, and the C part of the quad valve is divided into two line, one passes through the first electromagnetic valve and tray pipe of the indoor fan, and the other passes through the second electromagnetic valve, then the two lines combine into one, and there is a first double direction dry filter, a swell valve assembly, a second dry filter, and a liquid end head of the underground heat exchanger in sequence. The gas end head connects with the D part of the quad valve. Comparing to the traditional ground heat pump, this inventionion has no middle exchanger material and heat exchanger, the function of the system is improved.

Description

technical field [0001] The invention relates to a heat pump, in particular to a direct expansion ground source heat pump, and belongs to the technical field of central air-conditioning and hot water equipment. Background technique [0002] The heat pump is an environmentally friendly, efficient and energy-saving heating, air conditioning and domestic hot water equipment. This kind of equipment absorbs heat and cold energy from natural energy sources, and raises or lowers the temperature to meet the needs of building heating, domestic hot water or air conditioning. [0003] Ground Source Heat Pump (Ground Source Heat Pump, or Geothermal Heat Pump) uses low-quality energy in the shallow underground (including energy stored in groundwater, soil or surface water, etc.), and uses a small amount of electrical energy to air-condition and heat buildings. and hot water technology. Since a certain depth below the ground is basically a constant temperature layer, its temperature rang...
