Air energy heat pump commercial engineering machine installation specifications

Air energy engineering machine installation specifications

First, water tank location and fixing

Commercial aircraft water tank is generally installed on the ground or the roof, if installed on the roof, must consider the floor bearing the weight of the water tank installed on the roof of the corresponding bearing beam;

The water tank must be the foundation, which can be made of channel steel or cement, and the sewage outlet of the water tank must have a pipeline leading to the floor drain.

Second, host location and fixed

The main engine of commercial aircraft is usually installed on the ground or the roof. If the main engine is installed on the roof, the center of gravity of the main engine must be installed on the corresponding bearing beam on the roof. The wooden feet of the main engine must be removed before installation and the main engine must be fixed.

5P and above the host must be the foundation, can be used channel steel or cement foundation, and the last ditch near the host is made to facilitate the normal discharge of condensate water.

Third, distribution box location and fixing

According to the size of the distribution box can be divided into wall-mounted installation and floor-mounted installation, wall-mounted mostly used for smaller projects, wall-mounted installation is relatively simple and not subject to regional restrictions. Most of the floor type is used for large-scale projects, and the installation of the floor type is more complex and requires a position. There is no special requirement on the installation position of the power distribution box.

Lightning and rain protection devices must be installed on the distribution box. The wall-mounted type is directly fixed, and the ground-mounted type needs to be fixed as the foundation.

Fourth, pipeline layout

1. The circulating water inlet pipe is in the lower part of the water tank, but it must be higher than the hot water outlet pipe to ensure that the circulating water inlet pipe and the circulating water pump will not lead to the pump intake due to lack of water, resulting in insufficient water circulation to produce high pressure protection of the unit.

2, the distance between the main engine and the water tank is as short as possible.

3, the pipe between the main engine and the water tank to minimize the right Angle elbow.

4, the valve between the main engine and the water tank should be selected as far as possible ball valve and gate valve.

5, the pipe must be installed in accordance with the provisions of the bracket, the spacing is generally 1m-1.5m.

6, the height of the support is determined according to the site installation conditions, the pipeline is horizontal and vertical, and the bending degree is avoided as far as possible.

7, the bracket is made of Angle steel welding, coated with anti-rust paint, and the pipe card is fixed.

8, the support requires neat layout, consistent spacing, beautiful welding process.

Five, pipeline insulation

1, in addition to the tap water inlet pipe (water supply pipe) does not need to be insulated, other such as the circulating water pipe between the host and the water tank, hot water outlet pipe, return pipe, etc., need to be insulated.

2, insulation materials, generally use rubber and plastic sponge insulation materials, plus aluminum skin protection. With high and low temperature resistance, rain, heat preservation and other functions. And beautiful appearance. The thickness of the insulation layer is not less than 3cm.
